Relax. This problem can be worked out step-by-step. Find out how many moles are in 1.56 g of solid CO2. That is the volume per mole. To find out the volume per molecule, divide the volume per mole by Avogadro’s constant. Finding out the volume per mole and molecule for gaseous CO2 is very easy and they try to make it sound harder than it is. All gases at STP (273K 1 atm) are 22.4 L/mole, so there are 22.4 liters per every mole of CO2. For vol per molecule just divide 22.4 by Avogadro’s constant. Best of luck!
