A) 1.56 g
B) 0.408 g
C) 0.779 g
D) 13.1 g
E) 0.0487 g

Quizplus · Accepted Answer

The correct answer is A because 1.56 g of oxygen gas is required to occupy a volume of 6.00 L at a pressure of 20.9 kPa and a temperature of 37.0°C. This 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, and T is the temperature.
