A quantity of 18.0 mL of 1.30 M glucose solution is diluted to a new volume of 500. mL. What is the concentration, in mol/L, of the new solution?

Answer 1

V1M1 = V2M2

V1 = initial volume = 18.0 ml

M1 = initial molarity = 1.30 M

V2 = final volume = 500. ml

M2 = final molarity = ?

(18.0 ml)(1.30 M) = (500. ml)(x M)

x = 0.0468 M (3 sig. figs.)
