cos at ntp 1 mol of gas occupies 22400ml or 22400cm^3

nid404:
ok got it...thanks sir

nid404:
another 1 :P

The pressure exerted by a 12g of ideal gas at temp t degrees Celsius in a vessel V Litre is 1atm. When the temp is increased by 10 degrees at the same volume, the pressure increases by 10%. Calculate the temp t and voluume V.(molecular weight of gas=120)

ans
t=-173 degrees
V-0.82 L

nid404:
can some1 please answer.....i need to leave for my class in an hour...pleeeeaaaaaaase

0.1 mol of gas so pV=nRT so V=nRT/p=0.1*8.31*100/100000=8.31*10^-4 m3 or 0.83 ltres
