Jan 8, 2014 · MOLES FROM VOLUME OF SOLUTION. Molarity is the number of moles of a substance in one litre of solution. #color(blue)(bar(ul(|color(white)(a/a) M = n/Vcolor(white)(a/a)|)))" "# where #n# is the number of moles and #V# is the volume in litres. We can rearrange this equation to get the number of moles: #n = M × V# Example
Jun 19, 2019 · If given the mass of a substance and asked to find the number of atoms in the substance, one must first convert the mass of the substance, in grams, to moles, as in Example \(\PageIndex{1}\). Then the number of moles of the substance must be converted to atoms.
These relationships may be used to convert from grams to moles or vice versa; or from moles to atoms, molecules, or formula units or vice versa. In the next section, we will show how these relationships may also be used to count atoms, molecules, or formula units by weighing.
