Question

a weather balloon is inflated to a volume 2.2 10square3 L with 374g of helium. what is the density of helium in grams per liter

Answer 1

Density = 0.17 g/L

Step-by-step explanation:

It is given that,

Volume of the inflated balloon filled with Helium,
`V=2.2* 10^3\ L`

Mass, m = 374 g

We need to find the density of helium. It is equal to its mass per unit volume. It can be given by :

d =m/V

`d=(374\ g)/(2.2* 10^3\ L)\\\\=0.17\ g/L`

So, the density of helium in the balloon is 0.17 g/L.
