WebMay 1, 2010 · The formula can be used to calculate the number of moles of gases from a given volume or vice versa Simply cover the one you want and the triangle tells you what to do To find the volume Volume = Moles x Molar Volume Examples of Converting Moles into Volumes Table To find the moles Moles = Volume ÷ Molar Volume Webmass 1 = crucible + lid mass 2 = crucible + lid + magnesium mass 3 = crucible + lid + product This should allow them to calculate the mass of the mass of the magnesium (mass 2 – mass 1) and the mass of the product (mass 3 – mass 1). They could also calculate the increase in mass (mass 3 – mass 2), which corresponds to the mass of oxygen.
