Question

15 mL of a 0.16 M solution of glucose was diluted until the total volume reached 95 mL. What is the concentration of new solution?

Answer 1

the concentration of new solution = 0.025 M

Step-by-step explanation:

Given that :

The initial volume V_1 = 15 mL

Initial concentration M_1 = 0.16 M

Final volume V_2 = 95 mL

Final concentration M_2 = ???

We know that M_1 × V_1 = M_2V_2

Making M_2 the subject of the formulae; we have :

M_2 = (M_1 × V_1)/V_2

M_2 = (0.16 × 15)/ 95

M_2 = 0.025 M

Thus, the concentration of new solution = 0.025 M
