1.	The speed of sound in hydrogen at STP is V. The speed of sound in a mixture containing 3 parts of hydrogen and 2 parts of oxygen at STP will be
Answer» `V//2` `V//sqrt(5)` `sqrt(7)V` `V//sqrt(7)` Solution :`rho_(MIX)=(rho_(1)V_(1)+rho_(2)V_(2))/(V_(1)+V_(2))`, `(rho_(1))/(rho_(2))=(M_(1))/(M_(2))=(2)/(32)` `V PROP (1)/(sqrt(rho))implies(Vmix)/(V)=sqrt((rho)/(rho_(mix)))=sqrt((rho_(1))/(7rho_(1)))`
