A cars gas tank holds 15.2 gallons of gasoline (density = 0.66 g/ml). How many pounds of gasoline are present in a full tank?

To find the number of pounds of gasoline present in a car's full tank, we need to convert the volume of gasoline in gallons to the mass of gasoline in pounds. Here's how you can do that:

Step 1: Convert gallons to milliliters
Since the density of gasoline is given in grams per milliliter (g/ml), we first need to convert gallons to milliliters. We know that 1 gallon is equal to approximately 3,785.41 milliliters.

15.2 gallons * 3,785.41 ml/gallon = 57,508.032 ml

Step 2: Convert milliliters to grams
Using the density of gasoline (0.66 g/ml), we can convert the volume of gasoline in milliliters to grams.

57,508.032 ml * 0.66 g/ml = 37,902.55872 g

Step 3: Convert grams to pounds
Finally, we can convert the mass of gasoline from grams to pounds. We know that 1 pound is equal to approximately 453.592 grams.

37,902.55872 g / 453.592 g/lb ≈ 83.6067 lb

Therefore, the approximate weight of gasoline present in a full tank is 83.6 pounds.
