Whatisthe volumepecent of a solution prepared by dissolving15 cm^(3)of methanol in 100 cm^(3)of ethanol?

Answer»

Solution :Volumeof METHANOL = `15 CM^(3)`
Volumeof ethanol = `100 cm^(3)`
`therefore` volumeof the solution `= (15+100)=115 cm^(3)`
`therefore` volumeper centof solution= `(15)/(115)xx100=13.04%`
