What is the pressure in atmospheres if 1360.0g of N2O gas is compressed in a 25.0L cylinder and is stored in an outdoor shed where the temperature can reach 59.0°C in the summer?
According to this formula: PV = nRT when V = 25 L and n (mol) = 1360 g / 44 (mass weight of N2O)= 30.9 mol R constant = 0.0821 and T in kelvin =59 + 273 = 332 K By substitution in the formula: P* 25 = 30 * 0.0821 * 332 ∴ P = 32.7 atm
