Question

Calculate the gram molar mass of Ca3(PO4)2

Answer 1

Answer:

Ca3(PO4)2 = 3 Ca + 2 P + 8 O • Molar mass of Ca3(PO4)2 = • (3 x 40.08) + (2 x 30.97) + (8 x 16.00) = • 120.24 + 61.94 + 128.00 = • 310.18 g/mol or • 1 mol Ca3(PO4)2 = 310.18 g Ca3(PO4)2 • Example: Calculating Grams from Moles for Compounds • A student has worked out the details for an experiment that will use 0.115 mol
