A chemical storage unit suffers a spill of $18\text{ L}$ of acid. Emergency response rules state that $5\text{ L}$ of neutralizing liquid is needed per $1\text{ L}$ of spilled acid. How much neutralizing liquid is required in total?
  1. $23\text{ L}$
  2. $72\text{ L}$
  3. $90\text{ L}$
  4. $108\text{ L}$

Solution

Multiplying $18\text{ L}$ of acid by $5\text{ L}$ of neutralizing solution per liter gives $18 \times 5 = 90\text{ L}$.
