Flask Q (volume = 1.00 x 103 cm3 ) is filled with ammonia (NH3) at 102 kPa and 300 K. The tap is closed and there is a vacuum in flask P. (Gas constant R = 8.31 J K−1 mol−1 ) Calculate the mass of ammonia

This question can be solved using the ideal gas equation, given by: PV=nRT

Rearranging the ideal gas equation gives an expression for the number of moles as

n=PV/RT

Subbing the valu...
