Question

How many balloons can be filled from a single cylinder of gas?

Answer 1

Hi there

HEYA!!!


HERE IS YOUR ANSWER,



n = pV/RT n = (2.50x107 x (4x104/1003)) / (8.3 x 290) n = 415 moles of hydrogen in the gas cylinder ( this is correct from the mark scheme) However, I feel I have gone wrong with my next steps. I then found out the number of moles in one balloon of hydrogen. n = ((1.85x105 x (7.24x103/1003))/(8.3 x 290) n = 0.556 moles of hydrogen in one balloon I then simply did 415/0.556 to find out how many balloons I could fill, which gave me 746mol. The correct answer is actually 741mol

Well the total no. of balloons that could be filled from one cylinder of gas is :

→ 741 balloons.


THANK YOU.
