A clown at a birthday party has brought along a helium cylinder, with which he intends to fill balloons. When full, each balloon contains 0.00410 m3 of helium at an absolute pressure of 1.30 x 105 Pa. The cylinder contains helium at an absolute pressure of 2.40 x 107 Pa and has a volume of 0.00260 m3. The temperature of the helium in the tank and in the balloons is the same and remains constant. What is the maximum number of people who will get a balloon?
Check my working please don't know where I got wrong..,
#Figure out moles in cylinder:
PV=nRT, solve for n,
(2.40x10^7)*(0.00260)/(8.31)(T is nothing, cause it remains constant)
= 7509 moles in cylinder
#FIgure moles in each balloon:
nballoon = (.0041)*(1.3x10^5)/(8.31)(T is nothing cause it remains constant)
= 64.14
#Number of people = 7509/64 = 117 people, this answer is wrong...check and tell me where I went wrong and how to fix it please :)
