Volume: 12 L.
In order to determine the volume occupied by 1 g of hydrogen gas,
Before using this equation to solve for
Normal Temperature and Pressure (NTP) conditions imply a pressure of 1 atm and a temperature of
Plug in your values into the ideal gas law equation to get
I'll leave the answer rounded to two sig figs, despite the fact that you only gave one sig fig for the mass of hydrogen gas
