What volume is occupied by 0.250 mol of carbon dioxide gas at 25°C
and 0.488 atm?
A) 25.5 L B) 12.5L C) 12.5K D) 15.9L

B) 12.5L

Explanation:

-We apply the mixed Gas Law:

Where:

is the given pressure of the gas

is the volume of the gas

is the number of moles of the gas

is the ideal gas constant and temperature respectively.

#We make V the subject of the formula and substitute to solve for it;

Hence, the volume of the gas is 12.5 L
