WebThe 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 … WebEXAMPLE: Calculate the molar mass (gram formula weight) of a mole of aluminum sulfate, Al2(SO4)3. Round to 2 decimal places. 2 Al = 2 X (26.98) = 53. 96 . ... CHEMISTRY WORKSHEET # 5 MOLE PROBLEMS—MOLAR VOLUME OF A GAS. We have learned that a mole is a mass of material and number of particles. WebMolar mass is the amount of mass contained within a mole amount of a certain substance. Molar mass is usually given in units of grams/mole, or g/mol. So if you have a molecule with a molar mass of 10.00 g/mol then what it's telling you is that if you gather together a moles amount of those molecules, 6.02214076 x 10^(23) molecules, then it will ... google issuetracker
