sci.chem-molarity Calculator
Calculates solution molarity (mol/L) from solute mass, molecular weight, and solution volume, and performs dilution calculations. A 1 M NaCl solution contains 58.44 g/L — dilution: C₁V₁ = C₂V₂ gives the volume needed to reach a target concentration.
Inputs
Mass G
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
Molar Mass
Mass of one mole of the substance (g/mol). Found by summing atomic weights. Converts between grams and moles.
Volume L
Three-dimensional space occupied (m³ or L). 1 m³ = 1,000 L.
Results
moles
Quantity in moles. 1 mol = 6.022 x 10^23 particles. Moles = mass / molar mass.
molarity
Concentration in moles per litre (mol/L or M). Molarity = moles of solute / litres of solution. To dilute: C1V1 = C2V2.
g/L
