Question

PLEASE HELP!!

The molar mass of hydrogen gas (H2) is 2 g/mol. The molar mass of oxygen gas
(O2) is 32 g/mol. When the reaction starts with 32 grams of oxygen and a sufficient
quantity of hydrogen, how many moles of water are produced?

Answer 1

2 moles of H2O

Step-by-step explanation:

Molar mass of O2 is 32 g/mol so 32 g of O2 will equal (32 g)/(32 g/mol) = 1 mol

2H2 + O2 => 2H2O

according to the reaction, 1 mol of O2 will produce 2 mol of H2O.
