If you have a density of 3.0 g/mL and a volume of 10.25 mL, what is the mass?

mass = 30.75 g

Explanation:

mass = density × volume

mass = 3.0 g/mL × 10.25 mL

mass = 30.75 g

whats the meaning of /

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.
