How many moles are in the balloon

Reference no: EM13266211

A helium-filled balloon contains n = 1.1 moles of helium atoms at room temperature and a pressure P = 2 ? Patm (twice atmospheric pressure). Atoms are added to the balloon so that the pressure doubles to 4 ? Patm while the temperature and volume are kept fixed. How many moles are in the balloon?
