If gasoline has a density of 0.66 g/ml, what is the mass of 3 gal in kilograms

The mass of gasoline with a density of 0.66g/mL and volume of 3 gallons is 2.498kg.

HOW TO CALCULATE MASS:

The mass of gasoline can be calculated by multiplying the density by its volume as follows:Mass = density × volume According to this question, gasoline has a density of 0.66 g/mL, and a volume of 3 gal. The volume is calculated thus:Volume of gasoline in milliliters = 3785.41mLMass of gasoline = 3785.41mL × 0.66g/mLMass of gasoline = 2498.37gMass of gasoline in kg = 2.498kg

Therefore, link

The mass of gasoline in 3 gal in 7.5 kg.

Explanation:

It is known that 1 gallon is equal to 3785.41 ml of volume. So first the density of gasoline should be converted from g/mL to g/gallon.

As 1 gallon = 3785.41 ml

then 3 gal = 3 × 3785.41 = 11356.23 ml

As we know that density is the measure of mass occupied per unit volume. So here the volume is given as 11356.23 ml and the density is given as 0.66 g/ml.

Density = Mass/Volume

Since , volume and density is known the mass can be determined as product of density and volume.

Thus, Mass = 0.66 × 11356.23 g =7459.12 g = 7.5 kg.

So, the mass of gasoline in 3 gal in 7.5 kg.

The answer is a.
