the answer to your problem is A.Subscript...BRAINLIEST
Answer:
35.9%
Explanation:
The percent volume of the coffee solution can be calculated as follows:
% volume of coffee solution = volume of coffee/total volume of coffee solution × 100
According to this question, a cup of coffee has 71 mL of coffee and 127 mL of water. This means that, the total volume of coffee solution is;
71mL + 127mL = 198mL
% volume = 71/198 × 100
= 0.359 × 100
Percent volume of coffee solution = 35.9%
The purpose is that it shows you all the elements we know and it arranges them in groups that are also the same kind like Chemistry.
I believe it is D. because stoichiometry allows people to determine how much reactant is consumed in a chemical reaction.
