GPT 3.5
The total mass of the products can be determined by calculating the molar mass of each product and then multiplying it by the corresponding stoichiometric coefficient.
The molar mass of CO2 is 44 g/mol and the stoichiometric coefficient is 1, so the mass of CO2 produced is 44 g.
The molar mass of CaO is 56 g/mol and the stoichiometric coefficient is 1, so the mass of CaO produced is 56 g.
Therefore, the total mass of the products is 44 g + 56 g = 100 grams.
The molar mass of CO2 is 44 g/mol and the stoichiometric coefficient is 1, so the mass of CO2 produced is 44 g.
The molar mass of CaO is 56 g/mol and the stoichiometric coefficient is 1, so the mass of CaO produced is 56 g.
Therefore, the total mass of the products is 44 g + 56 g = 100 grams.
