Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the final pressure by using the Boyle's law as an inversely proportional relationship in pressure to volume at constant temperature:
Thus, we solve for our target, P2, to obtain:

The general formula for alkyne series is CnH2n-2
This is because alkyne is unsaturated hydrocarbon which has one triple bond and has no functional group from homologous series. Alkyne has a general formula of CnH2n-2
An example of an alkyne in ethyne with HC≡CH chemical formula ,
another example is propyne with CH3C≡CH formula
