Concept explainers
(a)
Interpretation:
The given statement is to be classified as true or false.
Concept introduction:
The atomic mass of an atom is the average of the total masses of the atoms in an element. Similarly, in case of molecules, the average mass of molecules is known as molecular mass. Formula mass is the mass of the atoms present in a molecular formula.
In a chemical compound, the proportion of atoms present in the compound is given by the empirical formula. Whereas the molecular formula represents the exact number of atoms present in the compound.
(b)
Interpretation:
The given statement is to be classified as true or false.

- 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?arrow_forwardAtomic masses are relative masses. What does this mean?arrow_forward1. Which of the following hydrocarbons has the highest mass percentage of carbon? methane, CH4 ethane, C2H6 propane, C3H8 butane, C4H10arrow_forward
- Complete the following table for TNT (trinitrotoluene), C7H5(NO2)3.arrow_forwardA compound associated with the odor of garlic on a persons breath has the chemical formula CyH8S and a formula mass of 88.19 amu. What number does y stand for in the chemical formula of the compound?arrow_forwardCarbonic anhydrase, an important enzyme in mammalian respiration, is a large zinc-containing protein with a molar mass of 3.00 × 104 g/mol. The zinc is 0.218% by mass of the protein. Determine how many zinc atoms each carbonic anhydrase molecule contains.arrow_forward
- Express the composition of each of the following compounds as the mass percents of its elements. a. formaldehyde, CH2O b. glucose, C6H12O6 c. acetic acid, HC2H3O2arrow_forwardIf Epsom salt, MgSO4 x H2O, is heated to 250 C, all the water of hydration is lost. On heating a 1.687-g sample of the hydrate, 0.824 g of MgSO4 remains. How many molecules of water occur per formula unit of MgSO4?arrow_forwardFor each of the following samples of ionic substances, calculate the number of moles and mass of the positive ions present in each sample. l type="a"> 4.25 g of ammonium iodide, NH4I i>6.31 moles of ammonium sulfide, ( NH4)2S i>9.71 g of barium phosphide, Ba3P2 i>7.63 moles of calcium phosphate, Ca3( PO4)2arrow_forward
- opical hydrocortisone is often used to treat a variety of skin conditions, such as insect bites, eczema, and rashes. Each molecule of hydrocortisone contains 21 atoms of carbon (plus other atoms). The mass percentage of carbon in hydrocortisone is 69.5 8%. What is the molar mass of hydrocortisone?arrow_forwardThe 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?arrow_forwardTo find the mass of a mole of an element, one looks up the atomic mass of the element in a table of atomic masses see Appendix III or the Periodic Table. The molar mass of an element is simply the mass in grams of that element that is numerically equal to its atomic mass. For a compound substance, the molar mass is equal to the mass in grams that is numerically equal to the sum of the atomic masses in the formula of the substance.
