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?
(b) If the volume is raised to 4.60 m3 and the temperature raised to 30.5°C, what will be the pressure of the gas?
I was able to get 173.81 for the mole present but I'm not able to get part (B)
