It is known that 28 grams of a certain ideal gas occupy 22.4 liters at standard conditions (0°C, 1 atm).The volume occupied by 42 grams of this gas at standard conditions is:
A)14.9 liters
B)22.4 liters
C)33.6 liters
D)42 liters
E)more data are needed

Question

Quizplus · Accepted Answer

The amount of gas (in moles) is directly proportional to the mass of the gas. Therefore, 42 grams of the gas is 1.5 times the amount of gas as 28 grams. As the volume is also directly proportional to the amount of gas (when pressure and temperature are constant), the volume of 42 grams of the gas at standard conditions would be 1.5 times the volume of 28 grams of the gas, which is 33.6 liters.
