2.00 g of hydrogen gas and 91.2 g of oxygen are placed in a 100L container. These gases react to form H20 gas

Question

THe temp is 38 deg Celsius at the end of the reaction.

What is the pressure at the conclusion of the reaction?

How do I figure this out?! I completely missed the lecture..>!

Answer 1

Oxygen is in excess.

H2 + 1/2 O2 -> H2O

So, only 1 g of O2 will be consumed.

Left = 90.2 g

So, P = nRT/V = (90.2/32)*0.812*(273+38)/100 atm.
