Asked by Bill

please I and my friend has been trying this one.
If there there are 2.7*10^19 molecules are there in 1.0cm3 of a gas at 273k and pressure 1.0*10 ^5Pa. How many molecules are there in 1.0cm3 of the gas at 350k and pressure 1.0*10 ^5Pa.

All you did was heat it up?
P V= n R T
so
n/V = density = P/RT
You tell me that P and V constant and so is R
so
n= k/T or (nT) = constant
so
2.7*10^19 * 273 = n * 350
n = 2.7 * (273/350) * 10^19
