Answer:
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%
