Solid C undergoes this reversible reaction when it is heated.
C(s)⇌A(s)+B(g)\mathrm{C(s) \rightleftharpoons A(s) + B(g)}C(s)⇌A(s)+B(g)
A sample of C is heated. Both products are collected without loss.
| Product | Mass produced (g) |
|---|---|
| A | 1.84 |
| B | 0.56 |
A and B are then placed together under conditions in which they react completely to form C.
Calculate the maximum mass of C that can be obtained from A and B.
Explain your answer.
