Explain % w/V and % w/w in brief.

Text Solution

Verified by Experts

Mass by volume percentage (% w/V) : It is the mass of solute dissolved in 100 mL of the solution. Another unit which is commonly used in medicine and pharmacy is mass by volume percentage.
Mass percentage (w/w) : The mass percentage of a component of a solution is defined as :
Mass % of a component `= ("Mass of the component in the solution")/("Total - mass of the solution")xx100`
For example, if a solution is described by 10% glucose in water by mass, it means that 10 g of glucose in dissolved in 90 g of water resulting in a 100 g solution.
Concentration described by mass percentage is commonly used in industrial chemial applications.
For example, commercial bleaching solution contains 3.62 mass percentage of sodium hypochlorite in water.
