Question

If 100 cubic centimetre of oxygen contains Y molecules, how many molecules of Nitrogen will be present in 50 cubic centimetre of Nitrogen under the same conditions of temperature and pressure.

Chapter :mole concept and stoichiometry.
Ans with clear steps. ​

Answer 1

Explanation:

Since, no. of molecules of a gas is directly proportional to volume at same condition of temperature and pressure

Therefore,

molecules of nitrogen = 50/100*Y = Y/2
