c=10 rho w/M

What you provide

What you provide

  • Solution density expressed in g/mL, using the same scenario as the other inputs
  • Solute mass percent expressed in %, using the same scenario as the other inputs
  • Solute molar mass expressed in g/mol, using the same scenario as the other inputs

What you receive

What you receive

  • Molarity in mol/L from the stated equation
  • A symbolic formula plus substituted working with your values
  • Visible assumptions, field guidance, and an authoritative learning reference

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

Density is in grams per milliliter, w is a numerical percent, and volumes are represented by bulk solution density.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
