Answer:
Density = 0.17 g/L
Explanation:
It is given that,
Volume of the inflated balloon filled with Helium, [tex]V=2.2\times 10^3\ L[/tex]
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
[tex]d=\dfrac{374\ g}{2.2\times 10^3\ L}\\\\=0.17\ g/L[/tex]
So, the density of helium in the balloon is 0.17 g/L.
