1 milliliter of carbon dioxide is under normal conditions. calculate the amount of substance and mass

1 mole of any gas under normal conditions has a volume of 22.4 liters.

The molar mass of carbon dioxide CO2 is 44 g.

Based on these data, it is easy to calculate the amount of substance and the mass of 1 ml3 of carbon dioxide.

1 ml3 = 10-6 liters, which means that it contains 10-6 / 22.4 = 4.46 * 10-8 mol of a substance or 1.96 * 10-6 g = 1.96 μg CO2.
