The formula that shows the correct representation of the combined gas law is; V1P1 / T1=V2P2 / T2
The combined gas law is obtained from the statements of Charles law and Boyle's law as follows;
Charles law; V/T = k
Boyle's law = PV = k
Combining the two I have; PV/T = k
For two masses of an ideal gas;
V1P1 / T1=V2P2 / T2
This is the statement of the combined gas law.

Answer:
17.689g
Explanation:
1: First, write out the equation you will follow:
Ca + S ⇒ CaS
2: Use the formula Mass = Mr x moles to work out the moles of both Ca and S - this will enable you to find the limiting reactant.
3: Moles Ca:
Moles = mass/ Mr = 15.3/ 40.1 = 0.382 moles.
4: Moles S:
Moles = mass/ Mr = 7.96/ 32.1 = 0.245 moles.
5: We now know S is the limiting reactant, and as there is a 1:1 ratio between S and CaS, there will also be 0.245 moles CaS.
6: Mass CaS:
Mass = Mr x moles = 72.2 x 0.245 = 17.689g
