What volume of oxygen gas is produced when 1.27 mol of water reacts completely according to the following reaction at 0°C and 1 atm?

The equation is: 2H2O = 2H2 + O2

Mole ratio H2O : O2 = 2:1

So, 1,27/x = 2/1, and x = 0.635 moles of O2

V = 22.4*0.635moles = 14.224 liters

Great!! can u do this one! i dont have time to post

A sample of carbon dioxide gas has a density of g/L at a pressure of 1.36 atm and a temperature of 56 °C.
