Question

the volume of gas at 0 c and 760 mm pressure is 22.4 . the no. of molecules present in this volume is ​

Answer 1

Answer:

2.041* 10^22    molecules

Explanation:

From ideal gas equation

PV=nRT

n=PV/RT            

760/22.4  * 22.4 *10^ -3 L /       (0.0821L atm/molK ×273)  

=0.03 mol×6.022×10^ 23  molecules

=2.041×10 22 molecules

2.041×10 22  molecules are present in the volume

let me know if i am wrong
