Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

(When answering this problem, report the answer with the appropriate number of significant figures. When entering units, use proper abbreviated units with proper capitalization.)A beverage drink mix sample is prepared by mixing a packet of beverage powder in a gallon (3.78 L) of water. A sample for analysis is prepared by diluting 10.00 mL of this solution in a 50.0 mL volumetric flask. A student calculates that the concentration of dye in the analyzed beverage mix solution is (2.59x10^-5) mol/L. Determine the mass (in grams) of food dye in the beverage mix packet. Hint: The answer is assumed to be reduced to the highest power possible.
3) An eager new legislator is enamored with how everything is expressed in powers of 10 in the metric system. In order to make chemistry calculations more straightforward, he has proposed introducing a “metric mole," defined as 1x1023, into the official educational standards. Explain in 3-4 sentences why this would be problematic using language that would be clear to someone who may not recall any chemistry past the middle-school level. 4) You fertilize egg cells from a healthy plant with pollen (which contains the male germ cells)
After creating her standard curve for absorption versus the concentration (M) of FD&C Red 40 and processing her data, Sally found that her drinking strength Kool-Aid sample had a concentration of 4.692 x 10–5 M. If 0.132 grams of Kool-Aid powder was used to prepare an 8-fl oz cup of her assigned flavor, what is the percent by mass of FD&C Red 40 in her Kool-aid powder? Report your answer as a percentage with two places after the decimal. Do not include the percentage sign in your answer. Pay attention to units. You are trying to find the mass percentage of red dye, so you need to know each variable in the equation in Appendix B. Note that the percent by mass equation should be multiplied by 100. There may be some useful conversion factors in the experimental procedure.
A student plots the graph of absorbance vs. concentration for their sample. They end up with a line with the equation y = 0.015x + 0.006. If the student finds the absorbance of the caffeine solution is 0.117, what would be the concentration of caffeine in mg/ml?
1a. Throughout the experiment, what are some possible sources of error that could have led to someone recovering a significantly smaller amount of table salt (NaCI) than was originally present in the sample mixture. 16. What are some possible sources of error that could have led to someone to appear to have recovered a significantly larger amount of sand (SiO2) than was originally present in the sample mixture.
In 2014 (the last year for which I can find data), Utah County had a carbon monoxide (CO) average concentration of 1.90 ppm. (1 ppm stands for 1 part per million which means in one million volumes of air—choose whatever volume unit you like—there would be one volume of carbon monoxide.) An average human takes inhales 0.50 L per breath and takes 20 breaths per minute. Carbon monoxide in the atmosphere has a density of 1.2 grams per liter. 2. How many liters of carbon monoxide will a person breathe in Utah County in 8 hours?

Calculate the edge length in m and the volume in L for a cubical box that will “exactly” contain 4.32x1023 atoms. Assume the diameter of the Argon atom is 3.4 Å (1.000 Å = 1.000x10-10 m). Assume the atoms touch each other so that the closest distance between atomic centers (nuclei) is 3.4 Å and the atoms fill the box with MANY layers of Argon atoms.Note: a cubical box needs only one measurement to be defined because each edge of a cube is exactly the same length, l,so that the volume of the box, V = l3.
