In
biology percentage solutions are often preferred to
molar ones. A 1%
solution would have 1g of
solute to 100ml of
solvent. This would be labelled as a weight/ volume [w/v]percentage solution. For w/w then both solvent and solute would need to be weighed in the required ratios. Volume would accordingly be measured using a
measuring cylinder[?],
volumetric flask[?],
pipette or similar.
Labels should show what the
percentage relationships are.
