⚗️ Molarity Calculator

Calculate concentration, mass, or volume for solutions

Solve For:

Quick Select Compound:

Molarity (Concentration)

Molecular Weight (g/mol)

Mass of Solute

Final Volume

M = mass (g) / (MW × Volume (L))

0.1711 M

M = 10.0000g / (58.44 g/mol × 1L) = 0.171116 M

Moles

0.1711 mol

mg/mL

% w/v

1.000%

📐 Key Formulas

Molarity

M = n / V = mass / (MW × V)

Mass Needed

mass (g) = M × MW × V(L)

Moles

n = mass (g) / MW

% w/v

% = (mass g / volume mL) × 100
