0.500 moles of an ideal gas has a volume of 0.0100 m³ and a temperature of 300 K. What is the pressure of the sample of gas? A) 125 kPa B) 143 kPa C) 157 kPa D) 198 kPa E) 217 kPa

Question

Quizplus · Accepted Answer

The pressure of the gas can be calculated using the ideal gas law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (8.314 J/(mol·K)), and T is the temperature in Kelvin. Substituting the given values: P = (0.500 moles * 8.314 J/(mol·K) * 300 K) / 0.0100 m^3 = 124.71 kPa, which rounds to 125 kPa.
