Find how many helium atoms are contained in the balloon

Reference no: EM13559600

A balloon is filled with helium at a pressure of 1.0 105 Pa.The balloon is at a temperature of 23°C and has a radius of0.18 m.

(a) How many helium atoms are contained in the balloon?

(b) Suppose we increase the number of helium atoms in the balloonby a factor of 5, keeping the pressureand the temperature fixed. By what factor does the radius of theballoon increase?
