How many moles of neon gas are present in a 10.0 L vessel, if the pressure of this gas equals 1.05 atm at 30 ° C?

Question

Quizplus · Accepted Answer

To find the number of moles of neon gas, we can use the ideal gas law equation: PV = nRT, where P is the pressure in atmospheres (atm), V is the volume in liters (L), n is the number of moles, R is the ideal gas constant (0.0821 L·atm/mol·K), and T is the temperature in Kelvin (K). First, convert the temperature from Celsius to Kelvin: T = 30 °C + 273.15 = 303.15 K. Then, rearrange the ideal gas law to solve for n: n = PV / RT. Substituting the given values: n = (1.05 atm) * (10.0 L) / (0.0821 L·atm/mol·K * 303.15 K) ≈ 0.422 moles Ne.
