Question

The density of unknown gas at 98°C temperature and 0.974 atm pressure is 2.5 x 10-3 then calculate molecular weight of gas.
Give correct answer :)​

Answer 1

solution:

density= 2.10× 10^-3g/ml=2.5 gl

PM = prt

0. 974 × 2.5 × 0.0821 × 371

=78.81

hope its help u

Answer 2

Answer:

it's out of my syllabus (￣ヘ￣;)

One simply measures the weight of a known volume of gas and converts this volume to its STP equivalent, using Boyle's and Charles' laws. The weight of the gas divided by its STP volume yields the density of the gas, and the density multiplied by 22.4 mol–1 gives the molecular weight.
