sci.molarity-calculator Calculator
Calculates molar concentration from dissolved mass and solution volume: c = n/V = m/(MW × V). A 1 M NaOH solution contains 40 g/L — serial dilution by 1:10 each time reduces concentration from 1 M to 1 mM in three steps.
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 Ml
Three-dimensional space occupied (m³ or L). 1 m³ = 1,000 L.
Results
molarity (M)
Concentration in moles per litre (mol/L or M). Molarity = moles of solute / litres of solution. To dilute: C1V1 = C2V2.
moles of solute
Quantity in moles. 1 mol = 6.022 x 10^23 particles. Moles = mass / molar mass.
normality (equiv/L)
Sample size or count used in the calculation.
ppm (mg/L)
Reference formula or conversion factor shown for context.
