Question

12 grams of an unknown gas exerts 2 atm pressure in a container of volume 5 dm^3 (Deci meter cube) at 227 degree Celsius. Calculate molar mass of unknown gas.
Please answer fast....

Answer 1

Explanation:

pv=nrt

2×5=12/mm×1/2×500

10=6/mm×1/2×500

mm=50×6=300

Answer 2

Answer:

The correct answer of this question is $300$

Explanation:

Given - $12$ grams of an unknown gas exerts $2$ atm pressure in a container of volume $5$ $dm^3$  at $227$ degree Celsius.

To Find - Calculate molar mass of unknown gas.

The ideal gas law can be used to determine the molar mass of an unknown gas if its temperature and pressure are also known. A specific process results in the creation of a gaseous nitrogen oxide.

Unknown gas is $12$ grams

$2$ atm pressure in a container of volume $5$ $dm^3$

$pv = nrt$

$2$ × $5 = 12/mm$ × $1/2$ ×$500$

$10 = 6 / mm$ × $1/2$ × $500$

$mm = 50$ × $6 = 300$

Molar mass of unknown gas is $300$
