Question

What is a decimolar solution?

Answer 1

Molarity

• Molarity is denoted by ‘M’ and is defined as the number of moles of solute in a litre solution.
• The unit of molarity is $\mathrm{mole}/\mathrm{liter}$ or $\mathrm{mol}/\mathrm{L}$.

Decimolar

• Decimolar solution refers to the solution with one by tenth molarity, i.e. $0.1\mathrm{M}$.
• For example, $0.1\mathrm{M}$ $\mathrm{HCl}$ is known as a decimolar solution of $\mathrm{HCl}$.
