- Percentage solution
biology, percentage solutions are often preferred to molar ones. A 1% solutionwould have 1 g of solutedissolved in a final volume of 100 ml of solution. This would be labeled as a weight/volume [w/v] percentage solution. For w/w, both solvent and solute would need to be weighed in the required ratios. Volume would accordingly be measured using a measuring cylinder, volumetric flask, pipetteor similar. Labels should show what the percentagerelationships are (w/v, w/w or v/v).
molarityof a percentage solution (w/v) can be calculated using the molar massof the soluteused. For example, sucrose(table sugar) has a molar massof a 342.34 g/mol. A 1% sucrose solution (100ml, w/v), therefore, is 0.029 molar, or 29 mM.
