Question

A student needs to mix 50 ml. of glycine with 950 ml. of distilled water.
This student has only a 25 ml. graduated cylinder. How many times will the
student have to use the cylinder both glycine and water to prepare the solution?

Answer 1

How much solution do you need? That's 950 mL + 50 mL = 1000 mL
(25 ml/time) x # times = 1000
Solve for # times.
