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.

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

did anyone actually do this? like if anyone has submitted this i rly need .
