N2 + 3H2 --->2NH3

If 6 liters of hydrogen gas are used, how many moles of nitrogen gas will be needed to completely react with the hydrogen gas at STP?

a. 89.6 mole
b. 0.089 mol
c. 0.179 mol
d. 0.402 mol

At STP, remember that 1 mol of gas occupies 22.4 L of volume.

Find the number of moles of hydrogen gas that you start with, and use the equation given to you to get the number of moles of nitrogen you need. Post what you get! :)
