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

Answer:

Density = 0.17 g/L

Explanation:

It is given that,

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

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

$d=\dfrac{374\ g}{2.2\times 10^3\ L}\\\\=0.17\ g/L$

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