Practice problems: 6. The following volumes of gases were collected over water. Correct each volume to the volume that the dry
gas would occupy at STP.
a. 871 cm3 at 12 °C and 84.1 kPa
b. 0.317 dm at 26°C and 115.7 kPa

b is the correct answer

mark me brainliest and hope this

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: )
