Moles of solution questions - The Student …

Moles = 3.65/36.5 = 0.1 (36.5 being the Mr of HCl) Volume = 100 cm^3 = 0.1 dm^3 (as you divide by 1000 to get from cm^3 to dm^3) Concentration = 0.1 / 0.1 = 1 mol dm^3 OK, so the mass of a solute within a given volume is its density. In terms of equation this is Density = Mass / Volume. You have the mass of HCl as 36.5 (molar mass).
