For example, salt is the solute in a salt water solution, and isopropanol or ethanol is the solute in a rubbing alcohol solution. Before working out moles of solute, you need to understand what a mole is. Molar Mass Calculator Common Compounds Periodic Elements Chemical Formula HCl also ...
Particularly, the molality of a solution is calculated using the number of moles of the solute and the mass of the solvent used expressed in kilograms.Answer and Explanation: The formula for the computation of molality is given as: {eq}Molality(m)=\frac{moles\, of\...
This is a calculator to convert from mass and molar mass to moles. This calculator can be used to find the moles of a solution where mass and molar mass are both known.
25.0 cm3 of a solution of strontium hydroxide was exactly neutralised by 15.00 cm3 of 0.100 mol dm–3 hydrochloric acid. Calculate the concentration, in mol dm–3, of the strontium hydroxide solution. b20.0 cm3 of a 0.400 mol dm–3 solution of sodium hydroxide was exactly neutralised by 25...
