Making up chemical solutions? Take the pain out of molarity and concentration calculations with this handy tool.

Calculate the amount of sodium hydroxide, NaOH, in 25.0 cm 3 of solution of concentration 0.1 mol/dm 3. If the amount in mol of a solute in a given volume of solution is known, its mass can also ...

Researchers can use a metric called the particle number concentration (PNC) to calculate the number of particles in a sample, ...

The concentration of a solution depends on the number of moles of the solute and the volume of the solution. You can therefore calculate the concentration of a solution in mol/dm 3 using the ...

Molarity vs Molality: Formula and Definitions Molarity measures solute per volume, molality per mass. Learn the key differences and how to calculate each.
