You have 163.8 g of phosphorus triiodide gas. What volume of gas do you have at STP?

Explanation:

We can convert the mass to moles and then use the Ideal Gas Law:

pV = nRT

1. Moles of PI₃:

2. Volume of gas

STP = 273.15 K and 1 bar

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
