Explanation:

Step1: Convert gallons to quarts

We know that 1 gal = 4 quarts. So for $3.72\times10^{- 2}$ gallons, the number of quarts is $3.72\times10^{-2}\text{ gal}\times4\frac{\text{quart}}{\text{gal}}=3.72\times10^{-2}\times4\text{ quart}=0.1488\text{ quart}$

Step2: Convert quarts to mL

Since 946 mL = 1 quart, then the number of mL is $0.1488\text{ quart}\times946\frac{\text{mL}}{\text{quart}} = 0.1488\times946\text{ mL}=141.7648\text{ mL}\approx141\text{ mL}$

Answer:

141 mL
