Question

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

Answer 1

Answer: 19.81 gallons

Step-by-step 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 = $4\times946.353=3785.412$ milliliter.

Using Unitary method ,

$\text{1 milliliter = }\dfrac{1}{3785.412}\text{ gallon}$

Then, $\text{75000 milliliters = }\dfrac{75000}{3785.412}\text{ gallon}$

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

Hence, 19.81 gallons water is needed.
