Problema Solution
A laboratory manager needs to buy 6L of acid. The acid is sold in 400 ML containers. How many containers does the laboratory manager need to buy?
Answer provided by our tutors
1 L = 1,000 ML
6 L = 6*1,000 ML = 6,000 ML
let x be the number of containers needed then:
400x = 6,000 divide both sides by 400
x = 6,000/400
x = 15 containers
the laboratory manager needs to buy 15 containers.
