A solution is prepared by dissolving 98.6 g of NaCl in enough water to form 875 mL of solution. Calculate the mass % of the solution if the density of the solution is 1.06 g/mL.

Answer 1

To find the mass % of the solution, we need to calculate the mass of NaCl and the mass of the solution.

Mass of NaCl = 98.6 g
Volume of solution = 875 mL
Density of solution = 1.06 g/mL

To find the mass of the solution, we can use the volume and density:

Mass of solution = Volume of solution x Density of solution
Mass of solution = 875 mL x 1.06 g/mL
Mass of solution = 927.5 g

Now we can calculate the mass % of the solution:

Mass % = (Mass of NaCl / Mass of solution) x 100
Mass % = (98.6 g / 927.5 g) x 100
Mass % = 10.64%

The mass % of the solution is 10.64%.
