0.723 moles of ZnO2 Would Weigh?
To find the weight of 0.723 moles of ZnO2 (zinc peroxide), we need to calculate its molar mass and then multiply it by the number of moles.
Molar Mass of ZnO2
Zn (zinc) = 65.38 g/mol
O (oxygen) = 16.00 g/mol (x2) = 32.00 g/mol
Molar mass of ZnO2 = 65.38 + 32.00 = 97.38 g/mol
Weight of 0.723 moles of ZnO2
Weight = Number of moles x Molar mass
Weight = 0.723 mol x 97.38 g/mol
Weight ≈ 70.39 grams
So, 0.723 moles of ZnO2 would weigh approximately 70.39 grams.
