This number, Avogadro's number, is 6.022x10 23. The mass in grams of one mole of a compound is equal to the molecular weight of the compound in atomic mass units. One mole of a compound contains 6.022x10 23 molecules of the compound.The mass of 1 mole of a compound is called its molar weight or molar mass.The units for molar weight or molar mass are grams per mole. Here is the formula for determining the number of moles of a sample:ne mole of a compound contains 6.022x10 23 molecules of the compound. The mass of 1 mole of a compound is called its molar weight or molar mass. The units for molar weight or molar mass are grams per mole. Here is the formula for determining the number of moles of a sample:
So the problem is that, when we compare amounts of one substance to another using moles, we must convert from grams, since this is the information we get from balances. There are three steps to converting moles of a substance to grams: 1  Determine how many moles are given in the problem.2  Calculate the molar mass of the substance. 3  Multiply step one by step two.roblem #1 - calculate how many grams are in 0.700 moles of H. Step One: The problem will tell you how many moles are present. Look for the word mole or the unit mol.. The number immediately preceeding it will be how many moles.
