A 6.55 g sample of calcium sulfide was decomposed into its constituent elements, producing 3.64 g of calcium and 2.91 g of sulfur. Which of the statements are consistent with the law of constant composition (definite proportions)? The ratio of calcium to sulfur will vary based on how the sample was prepared. The mass ratio of Ca to S in every sample of calcium sulfide is 1.25. The mass percentage of calcium plus the mass percentage of sulfur in every sample of calcium sulfide equals 100%. Every sample of calcium sulfide will have 3.64 g of calcium. Every sample of calcium sulfide will have 44.4% mass of sulfur.

3.116 The simplest approximate chemical formula for the human body could be written as C728H4850O1970N104Ca24P16K4S4Na3Cl2Mg. Based on this formula, describe how you would rank by mass the ten most abundant elements in the human body.
The element bromine is Br2, so the mass of a Br2 molecule is the sum of the mass of its two atoms. Bromine has two isotopes. The mass spectrum of Br2 produces three peaks with relative masses of 157.836, 159.834, and 161.832, and relative heights of 6.337, 12.499. and 6.164, respectively. (a) What isotopes of bromine are present in each of the three peaks? (b) What is the mass of each bromine isotope? (c) What is the average atomic mass of bromine? (d) What is the abundance of each of the two bromine isotopes?
The mass spectrum of phosphoryl chloride. POF3, is illustrated here. (a) Identify the cation fragment at a m/Z ratio of 85. (b) Identify the cation fragment at a m/Z ratio of 69. (c) Which two peaks in the mass spectrum provide evidence that the oxygen atom is connected to the phosphorus atom and is not connected to any of the three fluorine atoms?
Gallium arsenide, GaAs, has gained widespread use in semiconductor devices that convert light and electrical signals in fiber-optic communications systems. Gallium consists of 60.% 69Ga and 40.% 71Ga. Arsenic has only one naturally occurring isotope, 75As. Gallium arsenide is a polymeric material, but its mass spectrum shows fragments with the formulas GaAs and Ga2As2. What would the distribution of peaks look like for these two fragments?
The mass spectrum of bromine (Br2) consists of three peaks with the following characteristics: Mass (u) Relative Size 157.84 0.2534 159.84 0.5000 161.84 0.2466 How do you interpret these data?
Given that the density of argon is 1.78 g/L under standard conditions of temperature and pressure, how many argon atoms are present in a room with dimensions 4.0 m 5.0 m 2.4 m that is filled with pure argon under these conditions of temperature and pressure?
Boron consists of two isotopes, 10B and 11B. Chlorine also has two isotopes, 35Cl and 37Cl. Consider the mass spectrum of BC13. How many peaks would be present, and what approximate mass would each peak correspond to in the BCl3 mass spectrum?
The age of the universe is unknown, but some conclude from measuring Hubbles constant that the age is about 18 billion years old, which is about four times the age of Earth. If so, calculate the age of the universe in seconds. If you had a sample of carbon with the same number of carbon atoms as there have been seconds since the universe began, determine whether you could measure this sample on a laboratory balance that can detect masses as small as 0.1 mg.
