Answer:
34.21%
Explanation:
Given parameters:
Mass of ethylene glycol in the container = 130g
Mass of the liquid in total = 380g
Unkown:
Percentage of ethylene glycol in the liquid =?
Solution
To find the percentage of the ethylene glycol in liquid, we use the expression below:
Percentage of ethylene glycol in liquid = [tex]\frac{mass of ethylene glycol}{mass of liquid}[/tex] x 100
Percentage of ethylene glycol = [tex]\frac{130}{380}[/tex] x 100
Percentage of ethylene glycol = 34.21%
