Question 8
Get the volume of one balloon = 4/3 pi r^3
r = 2.1/2 dm
find out how many moles this balloon can accommodate at NTP ---convert volume into moles from the ratio at NTP
Now calculate moles present in the cylinder using PV= nRT equation
divide total moles of the cylinder / moles in one balloon to get the number of balloons.
maam the other day while discussing NTP and STP we came to the conclusion that they are same but many sites say they are different.Are they?
