The molar mass of naoh is 40.00 g/mol. if 5.20 g naoh are dissolved in 0.500 l of solution, what is the molarity of the solution? use mc009-1.jpg. 0.0125 m 0.260 m 3.85 m 7.69 m

Formulas:

1) M = n / V (in liters)

2) n = mass in grams / molar mass

Data:

Molar mass = 40.0 g/mol

mass = 5.20 g

V = 0.500 liter

Solution

n = 5.20 g / 40.00 g / mol = 0.13 mol

M = 0.13 mol / 0.5 liter = 0.260 M

0.260 M
