Answer: 40731.8 grams of this gasoline would fill a 14.6gal tank
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of gasoline = ?
Density of the gasoline =
Volume of the gasoline = 14.6gal = 55267.01 ml (1gal=3785.41ml)
Putting in the values we get:
Thus 40731.8 grams of this gasoline would fill a 14.6gal tank
The option in “the mass of 1me of carbon equals the mass of 1 mole of boron atoms” is false since
Mass=molesx molar mass
And the molar masses of these two elements are different so their masses aren’t equal
