Martha needs to determine the density of gasoline she has determined the mass to be 1250g and the volume to be 1500ml what is the density of the gasoline

We know that the equation for density is:

where D is the density, m is the mass in grams, and V is the volume.

Given two of the variables, we can then solve for density:

Therefore, we now know that the density of the gasoline is 0.833g/mL.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
