Calculate the mass of carbon dioxide released when 185.000 g of copper carbonate [molar mass = 123.5 g/mol] is heated (assuming that the reaction goes to completion). The molar mass of CO2 is 44.0 g/mol. Give your answer to three significant figures.

Answer:

The answer to your question is: 65.9 g released of CO2

Explanation:

MW CO2 = 44 g

MW CuCO3 = 123.5 g

CO2 released = ?

CuCO3 = 185 g

                            CuCO3     ⇒    CO2   +    CuO

                             123.5  -----------  44g

                             185 g -----------    x

                           x = (185 x 44) / 123.5

                           x = 65.9 g released of CO2

519.2 gram of carbon dioxide released when 185.000 g of copper carbonate is heated.

What is Stoichiometry ?

Stoichiometry helps us use the balanced chemical equation to measures quantitative relationships and it is to calculate the amount of products and reactants that are given in a reaction.

What is Balanced Chemical Equation ?

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

First, we have to write the balanced chemical equation

CuCO₃ → CuO + CO₂

123.5 gram CuCO₃  → 44 gram of CO₂

Then,

x gram of CO₂ = [tex]\frac{185 \times123.5}{44}[/tex]

                        = 519.2 gram

Thus, from above above conclusion e can say that 519.2 gram of carbon dioxide released when 185.000 g of copper carbonate is heated.
