a chemist is using 361 milliliters of a solution of acid and water. if 14.5% of the solution is acid, how many milliliters of acid are there? round your answer to the nearest tenth.
Answer
Explanation:
Step1: Convert percentage to decimal
$14.5%=0.145$
Step2: Calculate volume of acid
Multiply total volume by acid - percentage. $361\times0.145 = 52.345$
Step3: Round to nearest tenth
$52.345\approx52.3$
Answer:
$52.3$
