🤓 Based on our data, we think this question is relevant for Professor Leopold's class at UMN.

Solution: A balloon filled with 1.92 g of helium has a volume of 12.5 L. What is the balloon’s volume after 0.850 g of helium has leaked out through a small hole (assume constant pressure and temperature)?

Problem

A balloon filled with 1.92 g of helium has a volume of 12.5 L. What is the balloon’s volume after 0.850 g of helium has leaked out through a small hole (assume constant pressure and temperature)?

Solution

Remember the ideal gas law: PV = nRT

Constant pressure and temperature, R is also a constant
