Molarity Calculator

Moles of solute per liter of solution.

Mass to moles to concentration

Molarity is found in two steps: divide the solute's mass by its molar mass to get moles, then divide those moles by the total solution volume in liters.

The standard unit for solution chemistry

Molarity (M) is the default concentration unit in labs worldwide because it directly gives the number of reacting particles per liter — essential for titrations, dilutions, and reaction stoichiometry in solution.

Molarity

1.001 mol/L

What you entered

Mass of solute (g): 58.5Molar mass (g/mol): 58.44Solution volume (L): 1

1
Moles = mass ÷ molar mass
58.5 ÷ 58.44= 1.001 mol
2
Molarity = moles ÷ volume
1.001 ÷ 1= 1.001 mol/L

Result

Molarity: 1.001 mol/L

This solution is 1.001 mol/L (M).
