Assuming you did everything else right one potential mishap is this; The volume of the gas is in microliters uL and the temperature is in Celsius .If you didn't do so already, then convert temperature to kelvin, and the volume to liters. Before you do anything.

Ah I see they want the answer in microliters, uL I guess you could convert L back to uL just to be safe.

They give constant pressure; so 
PV = nRT becomes V = nRT so

V1/T1 = V2/T2

We need V2

V1T2/T1 = V2

Most importantly, do you understand how I got all of this so far?
