Calculate the mass percent of a NaCl solution in which 141 g of NaCl is dissolved in 4.00 L of water at 25 ∘C (density = 0.997 g/mL).

Express your answer numerically.

Solutions

Expert Solution

Mass percentage of NaCl in the solution is 3.60%.

The given data is

Mass of NaCl =149g

Water =4.0L

d =0.997 g/mL

So first we have to convert water in grams. In the given example it is in Litre.

Density is in g/ml

So convert 4 L to ml and is =4000ml.

Now needs to convert 4000ml to gram

By formula

Density = mass /Volume

Mass =density x Volume

Mass (g) =4000x0.997

= 3988 g.

Now we will calculate mass percentage of NaCl

Mass percentage= mass of solute/mass of solution

(Mass of solution is solute +solvent

That means NaCl +water)

Please find the calculation details in attached file.

Hope you clear the concept.
