What mass in kilograms of E85(d = 0.758g/mL) can be contained in a 11.5gal tank?

Convert 11.5 gallons to mL. 1 gallon = 3.785 L. Convert that to mL, then

mass in grams = volume x density
Then convert grams to kg.

To find the mass of E85 that can be contained in an 11.5-gallon tank, we need to convert the volume from gallons to liters and then use the density of E85 to calculate the mass.

1. Convert 11.5 gallons to liters:
1 gallon = 3.78541 liters (approximately)
11.5 gallons * 3.78541 liters/gallon ≈ 43.506 liters

2. Calculate the mass using the density of E85:
Density of E85 = 0.758 g/mL = 0.758 g/cm³

Mass = Density * Volume
Mass = 0.758 g/cm³ * 43.506 liters * 1000 cm³/L

Note: We multiply by 1000 to convert from liters to cm³.

Mass ≈ 32,966.7 grams

3. Convert grams to kilograms:
Mass in kilograms = 32,966.7 grams / 1000 kilograms/gram

Mass in kilograms ≈ 32.97 kilograms

Therefore, approximately 32.97 kilograms of E85 can be contained in an 11.5-gallon tank.

To find the mass of E85 that can be contained in an 11.5-gallon tank, we'll follow these steps:

1. Convert the volume of the tank from gallons to liters, as the density of E85 is given in grams per milliliter (g/mL).
- 1 gallon is approximately equal to 3.78541 liters.
- Therefore, the volume of the tank is 11.5 gallons * 3.78541 liters/gallon = 43.534 liters.

2. Convert the volume from liters to milliliters, as the density of E85 is given in g/mL.
- 1 liter is equal to 1000 milliliters.
- Therefore, the volume of the tank is 43.534 liters * 1000 milliliters/liter = 43,534 milliliters.

3. Calculate the mass of E85 using the density and volume.
- The density of E85 is 0.758 g/mL.
- Therefore, the mass of E85 is 43,534 milliliters * 0.758 grams/milliliter = 33,023.252 grams.

4. Convert the mass from grams to kilograms, as the question asks for the mass in kilograms.
- 1 kilogram is equal to 1000 grams.
- Therefore, the mass of E85 in kilograms is 33,023.252 grams / 1000 grams/kilogram = 33.023252 kilograms.

Therefore, the mass of E85 that can be contained in an 11.5-gallon tank is approximately 33.02 kilograms.
