Answer:
32
Step-by-step explanation:
There are two ways you can count the valence electrons.
A. From the Periodic Table
1 × P (Group 15) = 5
4 × O (Group 16) = 4 × 6 = 24
+3 e⁻ (for the charges) = <u> 3</u>
Total = 32
B. From the Lewis structure
In the <em>Lewis structure</em> (below), each line (bond) represents a pair of bonding electrons, and each dot represents an unbound electron (half a lone pair).
5 lines (bonds) = 5 × 2 = 10
3 single-bonded O atoms = 3 × 6 = 18
1 double-bonded O atom = <u> 4</u>
Total = 32

Explanation:
Hello,
In this case, even we are given two different gases, as it says "ensure that you run out of each gas at the same time", they shall behave as only one, for that reason, no matter the amounts, they are going to be modeled by means of the Boyle's law, as temperature remains unchanged, which allows us to understand the pressure-volume behavior as an inversely proportional relationship:
Hence, we solve for the P2, representing the pressure of the acetylene as shown below:
