Percent Concentration - Chemistry | Socratic
However, if we keep the mass of the solute at 10.0g and doubled the mass of the solvent (in this case, water), the concentration will be #c% = (10.0g)/(10.0g + 2*100.0g) * 100% = 4.76%# The same is true for percent concentration by volume, which is defined as the volume of the solute divided by the total volume of the solution and multiplied by 100%.
A solution of a metal hydroxide of formula MOH was prepared by dissolving 5.0g of MOH in 1 dm 3 of water (M is an unknown metal). 25 cm 3 of the MOH solution required 22.3 cm 3 of the HCl acid solution to neutralise it in a titration procedure using a pipette (MOH) and burette (HCl).
