If a tablet of acetaminophen, c8h9no2, weighs 324 mg, how many moles are there in the tablet? if a tablet of acetaminophen, c8h9no2, weighs 324 mg, how many moles are there in the tablet? 2.15 × 10-3 4.89 × 104 48.9 466 2.15

Explanation:

number of moles of C8H9NO2 =

The trick is to remember to convert milligrams to grams because molar mass is normally presented in grams per mole

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.
