PLEASE ANSWER ITS 32 POINTS!!!

Johnny has two balloons. He blew one up with his mouth (CO2) and then the other one with helium (He).

His little sister, Lisa does not understand why the one with helium floats, while the other one does not.

Solve for the molar mass of both CO2 and He to help explain why the balloon with He is able to float.

Respuesta :

Answer:

The molar mass of CO2 is 44.01 g/mol, whereas the molar mass of helium is 4.002602, since the mass is so much lighter for the helium it floats upwards because it is less dense than the air around it as well as being less dense than the CO2
