Question

The density of gasoline is 0.708 kg/L. What is the mass of 15 gallons of gasoline?

a) 10.62 kg
b) 11.28 kg
c) 12.42 kg
d) 13.35 kg

Answer 1

The mass of 15 gallons of gasoline is: c) 12.42 kg.

Step-by-step explanation:

First, we need to convert the volume from gallons to liters. There are 3.78541 liters in one gallon. So, 15 gallons is equal to:

15 gallons * 3.78541 liters/gallon = 56.78115 liters

Now, we can calculate the mass of the gasoline using the following formula:

Mass = Density * Volume

Mass = 0.708 kg/L * 56.78115 liters = 40.201 kg

Therefore, the mass of 15 gallons of gasoline is approximately 40.201 kg.

It's important to note that the answer choices are not evenly spaced and there is c) 12.42 kg. This can make it easy to select the wrong answer if you are not careful. The answer is option c.
