A sample of krypton gas is at a pressure of 1.62 x 103 kPa and a temperature of 26.5 ℃ in a rigid 30.0 L tank. How many moles of Kr does this tank contain?
Use the ideal gas law formula. PV = nRT P = 1.6 × 10³ kPa V = 30.0 L n = ? mol R = 8.314 L•kPa/K•mol T = 26.5 °C + 273.15 = 299.65 K Solve for n. n = PV/RT n = (1.6 × 10³ kPa × 30.0 L)/(8.314 L•kPa/K•mol × 299.65 K) = 19 mol (rounded to two significant figures) more+

What is the mass of a 285 ml sample of Krypton at 24 degrees C and 765 torr?
Consider the sample of Kr: Pressure, P = 765/760 atm Volume, V = 285 ml = 0.285 L Mass, m = ? g Molar mass, M = 83.8 g/mol Gas constant, R = 0.08206 L atm/ (mol K) Temperature, T = (273 + 24) K = 297 K PV = nRT and n = m/M Then, PV = (m/M)RT Hence, m = PVM/(RT) Mass of Kr, m = (765/760) × 0.285 ×...more+
