Calculate the number of moles of each compound, given the number of molecules. If you need to make a number a superscript, put a ^ in front of the number. For example, 2.45 x 1022 would be written as 2.45 x 10^22. 2.46 x 1021 molecules of CO2 10,000 molecules of H2O 8.75 x 1032 molecules of C6H12O6

-  4.08×10⁻³ moles of CO₂

-  1.66×10⁻²⁰ moles of H₂O

-  1453.5 moles of C₆H₁₂O₆

Explanation:

Let's determine the amount of molecules of each compound:

- 2.46×10²¹ molecules of CO₂

- 1×10⁴ molecules of H₂O

- 8.75×10³² molecules of C₆H₁₂O₆

1 mol  has 6.02×10²³ moles, so the rule of three will be:

NA of molecules are contained in 1 mol

- 2.46×10²¹ molecules of CO₂ are contained in (2.46×10²¹/ NA) =

- 1×10⁴ molecules of H₂O are contained in (1×10⁴ / NA) =

- 8.75×10³² molecules of C₆H₁₂O₆ are contained in (8.75×10³² / NA) =

-  4.08×10⁻³ moles of CO₂

-  1.66×10⁻²⁰ moles of H₂O

-  1453.5 moles of C₆H₁₂O₆

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.
