Answer:
0.01981 gallons.
Explanation:
In this problem, we need to convert 75 mL of water to gallons.
We know that, 1 gallon = 3785.41 mL
To convert 75 mL to gallons, we must use to the unitary method such that,
1 mL = (1/3785.41) gallon
So,
[tex]75\ mL=75\times \dfrac{1}{3785.41}\\\\=0.01981\ \text{gallons}[/tex]
So, there are 0.01981 gallons in 75 mL of water.
