Copyright 2023Water Education Foundation. For example, combine 0.05 kg of sodium (Na) with 25.000 grams of chlorine gas (Cl2) to form NaCl or table salt. Thus, we can read this reaction as "two moles of hydrogen react with one mole of oxygen to produce two moles of water." \text{number of moles} = \frac{\text{mass}}{\text{molar mass}}\\ It's part of dimensional analysis which lets you do successive conversions like this by either multiplying or dividing.
