If I have Oxygen gas at a pressure of 36.0 kPa, a volume of 38 L, and a temperature of 82 °C, how many moles of gas do I have? (Equation: K= 273+C),
PV=nRT
O 0.50 moles
O 0.40 moles
O 0.60 moles
O 0.46 moles

Respuesta :

Answer:

.46 moles

Explanation:

PV = n RT      make sure you use the correct R = 8.31446  L-kPa/(K-mol)

36 * 38 = n * 8.31446 * (273.15 + 82)

n = .463 moles
