So copper (II) sulfate pentahydrate has a molar mass of: (63.546 x 1) + (32.066 x 1) + (15.9994 x 4) + (1.0079 x 10) + (15.9994 x 5) = 249.6856 g/mol. We have 4.98 grams of the compound, so 4.98grams ⋅ ( 1mol 249.6855grams) = 0.019945mol

WebThe molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance's molar mass by summing the molar masses of its component atoms. We can then use the calculated molar mass to convert between mass and number of moles of the substance. Created by Sal Khan.
