A sample of an gas has a volume of 2.25 L at 286 K and 1.13 atm. What is the pressure when the volume is 1.89 L and temperature is 302 K?

The combined gas law holds that #(P_1V_1)/T_1=(P_2V_2)/T_2#. The amount of gas is assumed to be constant.


And so #P_2=(P_1V_1T_2)/(T_1V_2).#

The RHS expression clearly has the units of pressure as required, why?
