Chapter 1, Problem 1.95E

If 16.1 grams of an unknown metal occupy 4.66 cm^3, how many grams of the metal will occupy 11.3 cm^3?

To identify the substance, a chemist determined its density. By pouring a sample of the liquid into a graduated cylinder, she found that the volume was 35.1 mL. She also found that the sample weighed 30.5 g. What was the density of the liquid? What was the substance?

An antacid tablet weighing 0.938 g contained calcium carbonate as the active ingredient, in addition to an inert binder. When an acid solution weighing 56.404 g was added to the tablet, carbon dioxide gas was released, producing a fizz. The resulting solution weighed 57.129 g. How many grams of carbon dioxide were produced?

A cube of an unknown metal measures 0.250 cm on one side. The mass of the cube is 0.095 g. Which of the following is most likely the unknown metal? niobium 8.57g/cm^3 rhodium 12.4g/cm^3 copper 8.96g/cm^3 vanadium 6.11g/cm^3 zirconium 6.51g/cm^3

A pycnometer is a device used to measure density. It weighs 20.455 g empty and 31.486 g when filled with water (d=1.00 g/cm3). Pieces of an alloy are put into the empty, dry pycnometer. The mass of the alloy and pycnometer is 28.695 g. Water is added to the alloy to exactly fill the pycnometer. The mass of the pycnometer, water, and alloy is 38.689 g. What is the density of the alloy?

Ethanol has a density of 0.789 g cm‐3. Calculate the volume in mL that must be poured into a measuring cylinder to give 19.8 g of ethanol. Note 1 mL = 1 cm3.

A 46.60-gram pycnometer was filled with 100.50 grams of liquid. When filled with insoluble powder, the pycnometer weighs 84.60 grams. When the insoluble powder and liquid were combined, the pycnometer weighed 172.8 grams. If the density of the liquid is 0.85 g/cm3, what is the density of the insoluble powder? 2.1 g/cm3 26 g/cm3 3.1 g/cm3 O None of the Above FULI

A sample of metal pellets weighs 13.54 g. When this sample was placed in a 100-mL graduated cylinder, which contained 25.5 mL water, the new volume (of water and pellets combined) was 27.0 mL. If the metal is one of the solids listed in Table 1, what is the identity of the metal? Show your calculations and use the correct rules for determining significant figures in calculations as shown in the background section. Explain your identification.

According to the label on a bottle of salad dressing, the volume of the contents is 0.362 liter (L). Using only the conversions 1.00 L = 1000. cm^3 and 1 in. = 2.54 cm, express this volume in cubic inches.
