If 45.5 g of calcium carbonate is reacted with phosphoric acid, how many grams of carbon dioxide will be produced if the reaction yield is 85.0 %?

Answer 1

1. 2.017 moles of Ba(NO3)2 is equivalent to how many grams of NO3-?

Answer 2

N = 14 g/mol
O3 = 3*16 = 48 g/mol
so
NO3 is 62 g/mol
so
(NO3)2 is 124 g/mol

1.2017 * 124 =
