Question

A weather balloon holds 2,000 cubic meters of helium. The density of helium is 0.1765 kilograms per cubic meter. How many kilograms of helium does the balloon contain?

Answer 1

Approx. `350*kg`

Explanation:

`rho,"density"="Mass"/"Volume"`

And thus `"Mass"` `=rhoxx"volume"`

And here, `"Mass"` `=` `0.1765*kg*m^-3xx2000*m^3`

`=353*kg`
