Question

!!URGENT PLEASE!!

The equation for the formation of water from hydrogen gas and oxygen gas is 2H2+O2→2H2O . How many grams of water can be made from 64 g of oxygen gas?

Answer 1

Answer: 144 g

the mol of the oxygen gas is 64/16 = 4 (mol)

we have:

2H2 + O2 => 2H2O

           4  ------> 8

=> the mol of H2O is 8 mol

=> m(H2O) = 8.(2 + 16) = 8.18 = 144 (g)
