Question

What volume of a 0.33-m c12 h22 o11 solution can be diluted to prepare 25 ml of a solution with a concentration of 0.025 m?

Answer 1

Answer : When we are diluting a solution of
`C_(12) H_(22) O_(11)` from 0.33 m to 0.025 m of 25 ml we will need 1.89 ml of 0.33 m solution for the dilution.

Explanation : Using the formula
`m _(1)V_(1)=m_(2) V_(2)`

we can calculate the
`V_(1) = (25 X 0.025) / 0.33 = 1.89 mL`
