Question

Define the following modes of expressing the concentration of a solution. Which of these modes are independent of temperature and why?

w/w (mass percentage)

Long Answer

Solution

Mass percentage (w/w): it is a weight by weight relationship. Thus mathematically,

Mass % of a component = `"W of the component in the solution"/"W of the solution" xx 100`

where, W represent weight of the component or solution.
