A $0.005$ mol portion of anhydrous calcium carbonate is fully thermally decomposed, producing $100\ \text{cm}^3$ of gas. In a separate experiment, a $0.005$ mol portion of anhydrous calcium nitrate is also fully thermally decomposed under the same conditions. The volume of the gaseous products is then measured. What is the total volume of gaseous products obtained from the calcium nitrate?
- A$50\ \text{cm}^3$
- B$100\ \text{cm}^3$
- C$200\ \text{cm}^3$
- D$250\ \text{cm}^3$
