In the video, the water level was 15 milliliters before adding the chain, and 20 milliliters after adding the chain. When I weighed the chain, its mass was 68.2 grams. I believe the chain is solid metal (not gold plated), but is probably a blend of gold and other metals. I looked up that gold has a density of 19.3 g/ml, while the other metals like silver and copper usually blended with gold have a combined density of about 9.7 g/ml. Determine what percentage of the chain is gold, by mass, to at least 1 decimal place?

Before investigating the scene, the technician must dilute the luminol solution to a concentration of 5.00 x 10-2 M. The diluted solution is then placed in a spray bottle for application on the desired surfaces. How many moles of luminol are present in 2.00 L of the diluted spray? Express your answer with the appropriate units.
A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of dimethyl sulfoxide, glycerol, chloroform, acetone, and ethanolamine. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from her collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density dimethyl sulfoxide 1.1 olo 3 cm Ar glycerol 1.3 3 cm chloroform 1.5 3 cm acetone 0.79 3 cm ethanolamine 1.0 3
Water and rubbing alcohol have distinct properties and will react differently with the same substance. Observe these properties of water and rubbing alcohol: color, smell, and ability to dissolve salt. Record your observations in the table. To observe the solubility of salt in the liquid, put one-quarter teaspoon of salt into each container and stir. You may weigh out 1.5 g of salt on the electronic balance if you don’t have a one-quarter teaspoon measure. Observe the properties of the liquid in the container labeled unknown. Record the properties of the unknown substance in the table. Now observe the properties of the liquid in the container labeled unknown. Record the properties of the unknown substance in the table. Unknown Substance color smell solubility of salt Based on the observations, which liquid is the unknown liquid?
The questions is as follows: The World Health Organization drinking water standard for arsenic is 10.0 micrograms/liter. Los Angeles watter is 5 ppb (parts per billion) arsenic. Convert the WHO arsenic standard to ppb and determine whether Los Angeles water is above or below the standard. (Assume that the density of the water is 1.00 g/cm^3)
A student dissolves a Jefferson nickel to make 100.00 mL of solution in a volumetric flask. The student takes a 5.00 mL aliquot of the first solution and dilutes it to make 100.00 mL of a second solution. The student places a sample of the second solution in a cuvette for analysis using spectrophotometry. The molarity of the copper solution in the cuvette was determined by spectrophotometric analysis to be 2.90 x 10-2 M Cu. Calculate the mass of copper in the Jefferson nickel used to make the first solution. Use the diagram to help visualize the dilution process. WE IN GOD TRUST 100 mL LIBERTY 200 5 mL 100 mL cuvette

I’m stuck in this those question To make 1L of 250mM NaCl, I would add ——-grams of NaCl to a graduated cylinder and bring the volume to ——-mL. To make 50mL of 2% NaCl, I would add ANSWER grams of NaCl to a graduated cylinder and bring the volume to ANSWER mL. To make 200mL of 1x solution from a 10x stock, I would add ANSWER mL of 10x stock to a graduated cylinder and bring the volume to ANSWER mL.
You are given a "Gold Crown" to determine whether it is made of pure Gold or not. It has a mass of 675 grams when it is weighed in the air. Then it is submerged in oil (with density of 957 kg/m^3), it reads 640 grams. 7. Find the density of the Crown. Compare to the Gold density 19320 kg/m^3, is it really pure Gold?
A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of glycerol, carbon tetrachloride, pentane, tetrahydrofuran, and acetone. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from her collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density glycerol -3 1.3 g-cm - 3 1.6 g cm carbon tetrachloride -3 0.63 g·cm pentane tetrahydrofuran -3 0.89 g·cm -3 0.79 g·cm acetone Next, the chemist measures the volume of the unknown liquid as 0.786 L and the mass of the unknown liquid as 991. g. Calculate the density of the liquid. Round your g. cm answer to 3 significant digits. yes Given the data above, is it possible to identify the liquid? no glycerol carbon tetrachloride pentane If it is possible to identify the liquid, do so. tetrahydrofuran acetone
In an alternate reality, the following salinity vs. density information was collected and summarized below. Based on this data, calculate the salinity of a solution that has a density of 1.017 g/mL.
