Answer 1

This is a dilution problem. You should have learnt M₁V₁ =M₂V₂ formula where M represents concentration given here as Molarity (M).

They key here is to associate the initial volumes and concentration as either 1 or 2. If you plug the numbers in you will get the answer.

2.70M x V₁ = 1.25M x 0.330 L

The answer you get will be in liters

rearrange the equation....

0.153 L
