Answer:
1.428 moles
Explanation:
If 0.0714 moles of N2 gas occupies 1.25 L space,
how many moles of N2 have a volume of 25.0 L?
Assume temperature and pressure stayed constant.
we experience it 0.0714 moles: 1.25L space
x moles : 25L of space
to get the x moles, cross multiply
(0.0714 x 25)/1.25
1.785/1.25 = 1.428 moles
The number of moles of N2 should be 1.428 moles
Since there are the 0.0714 moles of N2 gas occupies 1.25 L space
Also, the volume is 25.0 L
So, here the no of moles should be
= (0.0714 x 25)/1.25
= 1.785/1.25
= 1.428 moles
Hence, The number of moles of N2 should be 1.428 moles
