One mole of an ideal gas at 1.00 atm and 0.00°C occupies 22.4 L.How many molecules of an ideal gas are in one cubic centimeters under these conditions?

Question

Quizplus · Accepted Answer

One cubic centimeter is equal to 0.001 L. Therefore, the number of molecules in one cubic centimeter can be calculated as follows:

n = (1 mol / 22.4 L) x (0.001 L) x (6.022 x 10^23 molecules/mol) = 2.69 x 10^19 molecules

Note that this calculation assumes that the gas behaves ideally at these conditions.
