Question

Please Urgent!! And please explain. :)

A chemist must dilute 87.0 mL of 1.61 M aqueous sodium carbonate (Na,Co,) solution until the concentration falls to 1,00 M. He'll do this by adding distilled water to the solution until it reaches a certain final volume.
Calculate this final volume, in liters. Round your answer to 3 significant digits.

Answer 1

0.140 Liter

Step-by-step explanation:

M1V1 = M2V2

M1 = 1.61 M

V1 = 87 ml

M2 = 1.00 M

V2 = ?

V2 = M1V1/M2

V2 = 1.61×87/1

V2 = 140.07 ml

V2= 0.140 L
