see what i mean this goes all so quikly in comparison with the other..... this questions is on gases.... the answer i am meant to be getting is 0.0227 m3 and im using the number of moles = gas / molar gas and getting confused

it says What volume is occupied by 1 mole of a gas at a pressure of 10^5 Pa at freezing point

use pV = nRT

V = nRT/P

= 8.31x1x273/1x10^5

= 0.0227

thats assuming freezing point is 0 celsius and its the 'freezing' point of water theyre talking about?

they are just being *******s as usual and trying to word it in a manner that puts others off, ok first off you need to come across the ideal gas equation Pv = Nrt p = pressure, v = volume, n = number of moles , r = some gay constant and t = temperature in kelvin

it wants volume so v = nrt / p

ok so it says freezing point, freezing point is zero degrees centigrade but you got to convert that into kelvin, so add 273.15 therefore t = 273.15

it gives you n , n = 1 and r = 8.3????? im not sure..... t , as we worked out is 273.15 and p = 10 to the 5

so v = 1 mol x 8.3 ( i think ) x 273.15 / 10 to the 5

which should give 0.0227 metres cubed you can do the calculation, i cant be bothered, remember to put the top part in brackets

the mole equation u mentioned is good, but id didnt give you the molar mass!

that was brilliantly xplained, muh teacher did say something about that equation u sed but only at the end of the lesson

Thats a shame, as its the only gas equation youll ever have to use in reality
