what is the density of co2(g) at stp?

44 g (1 mole) occupies 22.4 liters @ STP. Take it from there.

To calculate the density of CO2 gas (carbon dioxide) at STP (standard temperature and pressure), you need to know the molar mass and the volume of the gas at STP.

The molar mass of CO2 is 44 grams per mole. This means that 44 grams of CO2 correspond to one mole of CO2.

At STP, one mole of any ideal gas occupies a volume of 22.4 liters. Therefore, 22.4 liters of CO2 correspond to one mole of CO2.

Now, to find the density, you need to divide the mass of CO2 by the volume:

Density = mass/volume

Since we know that one mole of CO2 has a mass of 44 grams and occupies 22.4 liters, we can substitute these values into the formula:

Density = 44 g / 22.4 L

Calculating this, we get:

Density ≈ 1.964 g/L

Therefore, the density of CO2 gas at STP is approximately 1.964 grams per liter (g/L).
