1) What is the mole number of 6.72 liters of O2 gas at STP? 2) You have 4 mol of H2 gas at STP. How many liters is this?
Answer the following questions and type your solution in the box. Show all your calculations.
HINT: 1mol of any gas occupies 22.4 liters volume at STP (standard temperature and pressure) the formula is n= V/22.4 n is mole number, V is volume
