Part A A particular balloon can be stretched to a maximum surface area of 1257 cm². The balloon is filled with 3.2 L of helium gas at a pressure of 755 torr and a temperature of 288 K. The balloon is then allowed to rise in the atmosphere. Assume an atmospheric temperature of 273 K and determine what pressure the balloon will burst. (Assume the balloon to be in the shape of a sphere.) Express your answer using two significant figures. P = ΠΑΠ ΑΣΦ Submit Previous Answers Request Answer ? atm

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
