An ideal gas at 18.5°C and a pressure of 1.54 105 Pa occupies a volume of 2.10 m3.
(a) How many moles of gas are present?

(b) If the volume is raised to 5.30 m3 and the temperature raised to 31.0°C, what will be the pressure of the gas?

I used the formula pv = nRT
(1.54*10^5)(2.10m^3 = n(8.31)(18.5)
I did the the algebra and got 2103 moles, but that doesn't seem to be the answer. What am I doing wrong?
