WebThe relationship between two solutions with the same amount of moles of solute can be represented by the formula c 1 V 1 = c 2 V 2, where c is concentration and V is volume. Terms molarityThe concentration of a substance in solution, expressed as the number moles of solute per liter of solution. WebJan 7, 2014 · The official symbol for molarity is “c” (concentration), but many people use the old symbol “M”. M = n/V, 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 : How …
