IB Chemistry SL 1.4.3 Molar mass (M)
Use molar mass to move between mass and amount, then apply equation ratios to find reacting masses, solution volumes or an unknown M.
How this is tested
- calculate moles of O2 needed for complete combustion of a given mass of C3H8
- find reagent mass or volume from M, n, and the equation, e.g. H2SO4 needed for TlOH
- determine molar mass from measured mass and amount, e.g. 0.108 g / 0.00180 mol = 60.0 g mol^-1
