### Calculations for decompositions of a solid using gas laws under STP. How to use molecular masses and the given equation to find out the solution.

What volume of carbon dioxide at STP is produced by the complete decomposition of 24 g of CaCO3--2.69 dm3, 4.64 dm3,5.37 dm3, 7.68 dm3 To solve the question we write down the equation of the reaction: CaCO3 -----> CO2 + CaO This equation is balanced out. The number of atoms of every element is the same on the le
