This was homework question but i forgot to ask for help before

p.482 # 9

At STP, a container holds 14.01 g of nitrogen gas, 16.00 g of oxygen gas, 66.00 g of carbon dioxide gas, and 17.04 g of ammonia gas. What is the volume of the container?
I used table 12.1 on that page to solve this but i couldn't.
Thank you.

Figure out how many moles of each gas you have (remember Nitrogen, and Oxygen are diatomic) then use Avogadro's law n1/v1 = n2/v2 using n1 = 1 mol and v1 = whatever volume in table 12.1 and n2 is the number of moles you calculate. Then add up all the V2 values which will give you the correct answer.
