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?

the concentration of new solution = 0.025 M

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
