Quizplus · Accepted Answer

To find the pressure, use the ideal gas law: PV = nRT. First, convert 3.4 g of neon to moles (3.4 g / 20.18 g/mol = 0.168 moles). Convert 45°C to Kelvin (45 + 273.15 = 318.15 K). The volume is 0.250 L. Using R = 0.0821 L·atm/mol·K, solve for P: P = (nRT)/V = (0.168 mol * 0.0821 L·atm/mol·K * 318.15 K) / 0.250 L = 18 atm.
