How do you calculate the density of a gas, based on its temperature and pressure?

The overall chemical equation resulting from the sum of the following three steps is 2C (s) + 2H2O (g) → 2CO (g) + 2H2 (g) CO (g) + H2O (g) → CO2 (g) + H2 (g) CO (g) + 3H2 (g) → CH4 (g) + H2O (g) a. 2C (s) + 2H2O (g) → CO2 (g) + CH4 (g) b.
