Question

Calculate the molarity it’s, M, if a solution prepared by dissolving 20 g of NaCl in 1 L of water.

Solve-step-by-step

Answer 1

.3422 M

Step-by-step explanation:

Mole weight of NaCl ( from periodic table) = 58.439 gm/mole

20 g is how many moles ? 20 g / 58.439 gm/mole=.3422 mole

.3422 mole / 1 liter .3422 M
