What is the molar mass of a 1.25 g sample of gas that occupies a volume of 1.00L at a pressure of 0.961 ATM and a temp of 27°C

The molar mass of the gas is 32.03 g/mol

Explanation:

Pressure of gas = P = 0.961 atm

Volume occupied by gas = V = 1.00 L

Temperature = T = 27 = 300 K

Assuming M g/mol be the molar mass of the gas and the gas behaves as an ideal gas.

The ideal gas equation is shown below

Molar mass of given sample of gas = 32.03 g/mol

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: )
