QUESTION: Given 3.00 moles of krypton gas, Kr(g), how many liters will this sample occupy at STP?
a. 11.2
b. 22.4
c. 44.8
d. 67.2

ANSWER:

Step 1 of 2

At STP, all gases behave as an ideal gas and thus, the ideal gas equation is followed by each gas at STP.  The ideal gas equation governs an idea about the relationship between pressure, volume, moles, and the temperature of the gas.

Given information is: Moles (n) of Kr (g) is 3.00.

The Kr gas follows the ideal gas equation, and at STP the value of pressure is 101.325 kPa, the temperature is 273 K and the gas constant is 8.314 L kPa/ mol K.
