Determine the mass in grams of 3.60 × 10²¹ atoms of arsenic. (The mass of one mole of arsenic is 74.92 g.)
Solution
In chemistry, the molar mass of a matter is outlined because the mass of a sample of that compound divided by the number of substance therein sample, measured in moles.[1] The molar mass may be a bulk, not molecular, property of a substance. The molar mass is a mean of the many instances of the compound, which frequently vary in mass because of the presence of isotopes. most ordinarily, the molar mass is computed from the quality atomic weights and is therefore a terrestrial average and a operate of the relative abundance of the isotopes of the constituent atoms on Earth.
