Question

Calculate the number of moles of MCO3 that reacted with nitric acid given the equation of reaction as 2HNO3+MCO3~M(NO3)2+CO2+H2O

Answer 1

To calculate the number of moles of MCO3 that reacted with nitric acid, we need to know the stoichiometric ratio between MCO3 and HNO3.

From the balanced equation:

2HNO3 + MCO3 -> M(NO3)2 + CO2 + H2O

We can see that the stoichiometric ratio between MCO3 and HNO3 is 1:2. This means that for every 1 mole of MCO3, it requires 2 moles of HNO3.

Therefore, the number of moles of MCO3 that reacted with nitric acid is half the number of moles of HNO3 used in the reaction.

If you have the moles of HNO3 used, you can simply divide it by 2 to find the moles of MCO3 reacted.
