Question

If the volume occupied by 0.500 mol of nitrogen gas at 0°C is 11.2 L, then the volume occupied by 2.00 mol of nitrogen gas at the same temperature and pressure will be:
A. the data given is not sufficient to determine the volume
B. 22.4 L
C. 44.8 L
D. the same as that occupied by 0.500 mol of nitrogen gas

Answer 1

The  volume  occupied  by 2.00  moles of nitrogen  gas at  the same  temperature  and pressure  will be

 0.500  moles = 11.2 Liters
 what about 2 moles =? liters

by cross  multiplication

= 11.2 liters  x   2moles/ 0.500 moles  =  44.8  liters
