Question

How many moles are in 32.8 L of CO gas at STP?

Answer 1

At STP, 1 mole of any gas occupies 22.4 L of space. Since we are given STP conditions here, we can use this ratio to determine the number of moles of CO gas: (32.8 L CO)/(22.4 mol CO/L CO) = 1.51 mol CO.

So, there are 1.51 moles of CO gas.
