calculate the volume occupied by 7g of N2 gas at 27 degree c and 750mm Hg pressure
p v = n r t ... v = n r t / p
make sure the r value has the correct units
As we know that PV =nR T .................(1)eqn.
First of all, we will find n =given mass / molar mass
Then, put values in equation no. (1)
Make sure about value of R
Answer will be 6.239litres
