Find the pressure in atm of 20 g of neon gas at a temperature of 10 °C and a volume of 22.4 L. (Given: molar mass of neon = 20.18 x 10⁻³ kg mol⁻¹)

15. Find the pressure in atm of 20 g of neon gas at a temperature of 10 °C and a volume of 22.4 L. (Given: molar mass of neon = 20.18 x 10⁻³ kg mol⁻¹)

Step 1: Convert molar mass to g/mol and calculate the number of moles.
Given molar mass $M = 20.18 \times 10^{-3} \text{ kg mol}^{-1} = 20.18 \text{ g mol}^{-1}$.
Given mass $m = 20 \text{ g}$.
