Question

A solution is made by dissolving

3.60g of sodium chloride to a final
volume of 115mL solution.
What is the weight/volume % of the
solute?

Answer 1

3.13

Step-by-step explanation:

correct

Answer 2

3.13%

Step-by-step explanation:

Step 1: Given data

Mass of sodium chloride (solute): 3.60 g

Volume of solution: 115 mL

Step 2: Calculate the weight/volume % of the solute

We will use the following expression.

%w/v = mass of solute / milliliters of solution × 100%

%w/v = 3.60 g / 115 mL × 100%

%w/v = 3.13%

The weight/volume % of the solute is 3.13%
