So to use the balanced chemical equation to relate an amount of Cl2 to an amount of AlCl3, we need to convert the given amount of Cl2 into moles. We know how to do this by simply using the molar mass of Cl2 as a conversion factor. The molar mass of Cl2 (which we get from the ...
Now assuming that the mass gain is entirely caused by oxygen (molar mass of 16 g/mol), the molar mass of the starting material can be calculated with a simple ratio according to the following equation: (3.2)xgmol100%=16gmol65%=24.6g/mol which happens to be close to the tabulated ...

The molar mass of a gas can be computed with the ideal gas law, PV = nRT. The molar mass M can be introduced in the equation by first finding the relationship between M and n (number of moles), which is: n = m/M This is then plugged in PV = nRT to give: PV = mRT/M...
Equation relating M, m, d, and molar mass (mm) «on:April 05, 2013, 05:08:27 PM » How do I write an equation that connects the following variables: molarity (M), molality (m), density of solution (d), and molar mass of solute (mm)?
