Answer:
29.5%
Explanation:
Step 1: Given data
- Mass of ethylene glycol (solute): 124 g
- Mass of liquid (solution): 420 g
Step 2: Calculate the mass percentage of ethylene glycol in the liquid
We will use the following expression.
%m/m = mass of ethylene glycol/ mass of solution × 100%
%m/m = 124 g/420 g × 100% = 29.5%
The mass percentage of ethylene glycol in the liquid is 29.5%.
