Stoichiometry : Molar Mass Quiz
The mass in grams of one mole of any substance is its molar mass. The molar mass of any element is numerically equal to its atomic mass. For instance, one mole of oxygen has a mass of 15.99g./mol One mole of fluorine gas has a mass of 18.99g/mol. To find the mass of a compound, you must add up the individual masses of its component elements. For example, table salt (NaCl) has two elements. The molar mass of sodium is 23g/mol. The molar mass of chlorine is 35.5g/mol. So when you add those together, you get the molar mass of salt, which is 58.5g/mol. This quiz will cover the computations of the molar mass of compounds. You will need a calculator and a periodic table. Select the best answer from the given choices.
