Question

calculate the mr of calcium carbonate, \\(\text{caco}_3\\). \\(\text{ar}: \text{ca} = 40, \text{c} = 12, \text{o} = 16\\).

calculate the number of moles in \\(10.0\text{ g}\\) of \\(\text{caco}_3\\).

\\(\text{caco}_3\\) decomposes: \\(\text{caco}_3(\text{s}) \
ightarrow \text{cao}(\text{s}) + \text{co}_2(\text{g})\\). use the equation to find the moles of \\(\text{cao}\\) formed.
