Chemistry help involving mixture and its partial pressure?

Okay here're some basics first (if you understand these just skip to the bottom).

Moles = amount of a substance. Just like we can measure grams to measure amount, moles is another such measure except that it takes the actual weight (in grams) and divides by the substance's atomic/molecular weight - kinda makes everything standardised.

Partial pressure is just the fraction of the total pressure that a certain gas produces. (Every gas produces a pressure). So if we know the fraction of *amounts* of the gases in a mixture, we can still find the fraction of the *pressure* of a certain gas like so:

Partial pressure of neon = fraction of neon in mixture x total pressure

Fraction of neon = 5.00 / (5.00 + 3.00) = 5/8

So partial pressure of Neon = 5/8 x 6.00 atm

= 3.75 atm.

Partial pressure of a gas = (number of gas moles/number of mixture moles) x total pressure

partial pressure of Neon = (5/8) x 6 = 3.75 atm
