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)
Advertisements
उत्तर
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.
