May 19, 2017 · Copper has a molar mass of 63.546 g mol−1, which means that 1 mole of copper has a mass of 63.546 g. Now, in order to have 1 mole of copper, you need to have 6.022 ⋅ …

65.0 "g N"_2 Any time you want to convert between moles and grams of a substance, you must know that substance's molar mass, which is the mass of one mole of that substance. (One …

(a) Use the molar mass to convert the mass of NaN3 to moles of NaN3. (b) Use the molar ratio (from the balanced equation) to convert moles of NaN3 to moles of N2.

To find the number of moles, we need the mass and the molar mass. The molar mass is given by the sum of the individual molar masses of the constituent atoms in the molecule.
