Question

1. How many moles of Na and Cl₂ are required to make 585 grams of NaCl?

_________ mol Na        _________mol Cl₂

Answer 1

yNat d, 2 Nau. Molar mass of Nad = 58.5 g/mol Let xl be the number of moles of Na required to produce 585g of Nad 2 moles of Na gives → 2X58.5 g of Nach lx' moles of Na gives - 5859 of Nad. cross multiply 28585 = 58.5 X X X2 x= 10 moles of Na= 10 moles Let cys be the number of moles of ų required to produce 585 g of Nall I mole of ų givu + 2x 58.5 g of Nach cy' moles of U, gives - 585 g of way. cross multiply 585 = 2X58-5xy y = 5 moles of a
