What is the volume if we have 0.5 moles of CO2 at 28 °C with a pressure of 10 atm?

A mole of an ideal gas at 273 K in a volume of 22.4 L will have a pressure of 101.3 kPa. What would the pressure be for a mole of protons in a... The temperature of an ideal gas is increased by 1°C from 250 K, keeping the volume constant. What is the percentage increase in pressure?

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!
