Question

The mass of fuel in a jet must be calculated before each flight to ensure that the jet is not too heavy to fly. A 747 is fueled with 173,231 L of jet fuel. If the density of the fuel is 0.768 g/cm3, what is the mass of the fuel in kilograms (kg)? (11 = 1000 cm3)

Answer 1

The mass of the jet fuel is 133,029.408 kg.

Step-by-step explanation:

To calculate the mass of the fuel in kilograms, we can use the formula:

Mass = Density x Volume

First, we need to convert the volume of jet fuel from liters to cubic centimeters (cm3) because the density is given in grams per cubic centimeter. We know that 1 liter is equal to 1000 cm3, so the volume of the fuel in cm3 is 173,231 L x 1000 cm3/L = 173,231,000 cm3.

Next, we can calculate the mass by multiplying the volume by the density:

Mass = 173,231,000 cm3 x 0.768 g/cm3 = 133,029,408 g = 133,029.408 kg
