A)0.0456
B)0.262
C)0.295
D)3.82
E)7.65

Question

Quizplus · Accepted Answer

The density of a gas can be calculated using the ideal gas law rearranged to the form: density = (P * M) / (R * T), where P is pressure, M is molar mass, R is the ideal gas constant, and T is temperature in Kelvin. For krypton, with a molar mass of approximately 83.8 g/mol, at 1.21 atm and 323 K (50°C), the density is approximately 3.82 g/L.
