An aqueous nabr solution has a mass of 270.0 g and contains 27.50 g nabr. calculate the mass percent nabr .

The mass percent of NaBr in the solution is 10.18 %

Explanation:

To calculate the mass percentage of calcium ions in milk, we use the equation:

We are given:

Mass of solution = 270.0 g

Mass of NaBr = 27.50 g

Putting values in above equation, we get:

Hence, the mass percent of NaBr in the solution is 10.18 %
