Answer:

5.60 Liters at STP

Explanation:

First you need the balanced reaction equation

2 H2 + O2 ====> 2 H2O

4 g of oxygen ( O2 ) is 4/(15.999*2) moles of O2 (using periodic table)

Twice the number of moles of H2O re produced (from equation)

at STP the volume of a mole of gas is 22.4 liter/ mole

put all of this together

2 * 4 / (15.999*2) moles * 22.4 L/mole = 5.60 L
