Step-by-step explanation

Algebra / Percent / Percent Problems

From the statement, we know that:

• the chemist is using S = 378 ml of solution,

,

• a percentage of p = 16.8% = 0.168 of the solution is acid.

We want to know how many ml of acid are in the solution.

The number of ml in the solution that are acid is given by:


A=p\cdot S=0.168\cdot378ml=63.504ml\cong63.5ml.Answer

63.5 ml of the solution are acid.
