Question

A dialysis unit requires 75000 mL of distilled water. How many gallons of water are needed?

Answer 1

Answer: 19.81 gallons

Explanation:

Given : A dialysis unit requires 75000 mL of distilled water.

We know that 1 gallon= 4 quarts

and 1 quart= 946.353 ml

Then, 1 gallon =
`4*946.353=3785.412` milliliter.

Using Unitary method ,

`\text{1 milliliter = }(1)/(3785.412)\text{ gallon}`

Then,
`\text{75000 milliliters = }(75000)/(3785.412)\text{ gallon}`

`=19.8129132643\approx19.81\text{ gallons}`

Hence, 19.81 gallons water is needed.
