Answer: 13.33 gallons of water
Step-by-step explanation:
In a certain state a hospital is required to use 3% bleach to clean dishes. Let the volume of the bleach used
We are having a 20 gallons of 5% bleach. This concentration is higher than what the hospital required. We want to dilute it with water to reduce the concentration of the bleach from 5% to 3%.
To do this,we use the formula,
C1V1 = C2V2
C1, initial concentration of the bleach
= 5% = 5/100 = 0..05
V1 = initial volume of the mixture =20 gallons
C2 , final concentration of the bleach
= 3% = 3/100 = 0.03
V2 = final volume of the mixture in gallons
0.05 × 20 = 0.03 × V2
1 = 0.03V2
V2 = 1/0.03 = 33.33 gallons of mixture
Amount of water = 33.33 - 20 gallons of bleach = 13.33 gallons of water
