# Amount of substance question watch

1. How would u answer the following question???

The removal of silicon dioxide with limestone in the blast furnace can be represents by the following equation. CaCO3 (s) + SiO2 (s) > CaSiO3 (l) + CO2 (g)
The volume of carbon dioxide, measured at 298k and 1.01x 10^5 pa, formed in this reaction during the removal of 1.00 tonne (1000kg) of silicon dioxide is?

Correctly, I would hope.

3. Stoichiometry is 1+1 = 1+1

Using Mr of SiO2 (g), find how many moles in 1.0 tonne.

mass of SiO2 (g) / Mr of SiO2 = # moles of SiO2

# moles of SiO2 = # moles of CO2

PV = nRT, therefore V = nRT / P, find V.
