Because you need 2 mols of Na to produce 1 mol of Na2s you would need 4 mols of Na to produce 2 mol of Na2s. They remain proportional.
2 Na + S = Na2S
2(2 Na + S) = 2 (Na2S)
4Na + 2S = 2 (Na2S)

The equation you are given yields one mole of Na2S. Simply double the ratios to end up with 2 moles of Na2S:
2Na (x2) + S (x2) –> Na2S (x2)
You now have: 4Na + 2S –> 2Na2S
Therefore, your answer would be 4 moles of sodium (Na).

something is incorrect in this problem. we can’t have floor section in cm^3. whether that’s cm^2 you will discover out optimal quantity of the balloon at which it may burst. because of the fact the balloon rises rigidity decreases and quantity will improve. P1V1=P2V2. P1 V1 is given first you discover out V2 as above. Then replace those values and get P2.
