Molarity is the concentration of a solution in terms of the number of moles of the solute in 1 dm 3 (1 liter) of the solution. What are the units of molarity? The units of molarity are M or mol/L. A 1 ...

One mole contains the same number of particles as there are atoms in 12 g of carbon-12. As atoms and molecules are so small, the number of particles in a mole is very large. This number is: ...

The mass of a given number of moles of substance is calculated using: \(mass~in~g = \textit{M}_{\textup{r}}\times~number~of~moles~or~mass =\textit{M}_{\textup{r ...
