An aqueos solution is 65%(v/v) rubbing alcohol.How many millimeters of water are in a 95mL sample of this solution?

Technically, none since there are no mm in a mL.
65% alcohol (v/v) means 65 mL alcohol in 100 mL solution. It must be 35% water.
That is 35 mL H2O/100 mL so in 95 mL we have 35 x (95/100) = ??
