Question

A metal x with relative atomic mass 56 form an oxide with formula X2 O3 how many grams of metal will combine with 10g of oxygen:?(O=16)

Answer 1

10 g x (4*atomic mass X/3*molar mass O2) = ?

Answer 2

56 *2 112g X will react with 3*16 = 48g O

10g O will react with 10gO / 48gO * 112gX =23.3g X
