Molarity from Mass Calculator

Find molarity from solute mass, molar mass and volume.

Solute mass

Molar mass (g/mol)

Solution volume

Calculated Output

Molarity (mol/L) 0.1001

Moles (mol) 0.1001

Formula: molarity = (mass ÷ molar mass) ÷ volume

Step-by-Step Breakdown

1. Values used:

2. Solute mass = 5.85

3. Molar mass = 58.44 g/mol

4. Solution volume = 1

6. Molarity = Solute mass / Molar mass = 5.85 / 58.44 = 0.1001mol/L

7. Moles = Solute mass / Molar mass = 5.85 / 58.44 = 0.1001mol

Did this calculator solve your problem today?

The math behind it

moles = mass ÷ molar mass; molarity = moles ÷ volume (L).

5.85 g NaCl (58.44) in 1 L → 0.1 M.
