A difference In density between gases creates buoyancy which is the ability of an object to float. 0°C helium has a density of .18 kg/m³. 0°C regular air has a density Of 1.29 kg/m^3.
In kilograms how much mask in a cubic meter of helium float in regular air at 0°C?
Answers: 1
![density = \frac{mass}{volume} \\\\where:\\volume = 1 [m^3]\\density = 0.18[kg/m^3]](/tpl/images/0561/3911/ebb1c.png)
