The answer is 39.2L.

The gas laws tell us that all ideal gasses behave identically under the same conditions. At STP, the molar volume of any ideal gas is equal to Vmolar=22.4L, which means that 1 mole of any gas at STP will occupy exactly 22.4L.

Therefore we can determine the volume occupied by any number of moles of any ideal gas at STP by using

n=VVmolar, which results in V=nVmolar=1.75moles22.4L1mole=39.2L
