An unknown gas diffuses 5 times less than that of H2.what is the molec

1.	An unknown gas diffuses 5 times less than that of H2.what is the molecular mass of the unknown gas?
Answer» answer is 50 Explanation: the rate of DIFFUSION of H2 gas =r2 the rate of diffusion of unknown gas ,r1=5r2 molecular mass of unknown gass =M1 molcular mass of H2 gas=2 rate of diffusion =√molecular mass of unknown gas /Molecular mass of H2 gas r1/r2=√M1/2 5r2/r2=√M1/2 5/1=√M1/2 squaring on both sides 25/1=M1/2 M1=50 i hope it is helpful!!

Answer»

answer is 50

Explanation:

the rate of DIFFUSION of H2 gas =r2

the rate of diffusion of unknown gas ,r1=5r2

molecular mass of unknown gass =M1

molcular mass of H2 gas=2

rate of diffusion =√molecular mass of unknown gas /Molecular mass of H2 gas

r1/r2=√M1/2

5r2/r2=√M1/2

5/1=√M1/2

squaring on both sides

25/1=M1/2

M1=50
