An ideal gas at 6.0°C and a pressure of 1.92 105 Pa occupies a volume of 2.10 m3.
(a) How many moles of gas are present?
moles

(b) If the volume is raised to 4.60 m3 and temperature raised to 30.5°C, what will be the pressure of the gas?
Pa

I used the formula n= (pv)/rt
which r is = 8.31
but I'm not coming up with right answer (19200)(2.10)/(8.31)(6.0) can you tell what I am doinf wrong.

You should convert the temperatures of Kelvin. Also pressure is 192000 N/m^2
