A sample of gas at 47°C and 1.03 atm occupies a volume of 2.20L. What volume would this gas occupy at 107°C and 0.789 atm? Does your answer make sense in terms of the gas law relationships?

Answer 1

PV=kT, so you want V such that
0.789V/(273+107) = 1.03*2.20/(273+47)

the question about making sense seems kind of unnecessary, since the only way to arrive at the answer would be to use the gas laws.

However, whenever you solve a problem, a sanity check on the answer should always be done.
