Gasoline, if 9.00 liters has a mass of 6120 g. Find the density in g/cm^3

The density of gasoline is 0.68 g/cm³.

Explanation:

Given data:

Volume of gasoline = 9.00 L

Mass of gasoline = 6120 g

Density of gasoline = ?

Solution:

first of all we will convert the unit, L to mL.

9.00 L × 1000 mL / 1 L = 9000 mL

Formula:

d = m/v

d = density

m = mass

v= volume

d = 6120 g/ 9000 mL

d = 0.68 g/cm³  ( mL =cm³ )

Thus, density of gasoline is 0.68 g/cm³  .

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
