A mixture of gases contains H_(2) and O_(2) gases in the ratio of 1:4 (w//w). What is the molar ratio of the two gases in the mixture?

Answer»

`16:1`
`2:1`
`1:4`
`4:1`

SOLUTION :Suppose `H_(2)=W`, then `O_(2)=4wg`
MOLES of `H_(2)=(w)/(2)", Moles of O"_(2)=(4w)/(32)=(w)/(8)`
`"MOLAR ratio of "H_(2):O_(2)=(w)/(2):(w)/(8)=(1)/(1):(1)/(4)=4:1`
