Answer 1

Answer:

The hot cocoa made by Eli will be more chocolatey

Step-by-step explanation:

To find wose hot cocoa Is more chocolatey we need to find the percentage of concentration in both of them

Concentration in Arjun's hot cocoa

Chocolate syrup- 20 ml

Hot water - 90 ml

Now the total amount of solution is - 20 + 90 = 110

Using the forumala = quantity of solvent / Quantity of solution *100

We get the answer as = 18.18%

Concentration in Eli's hot cocoa

Chocolate syrup- 45 ml

Hot water - 180 ml

Now the total amount of solution is - 45 + 180 = 225

Using the forumala = quantity of solvent / Quantity of solution *100

We get the answer as = 20%
