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](https://tex.z-dn.net/?f=V%3D2.2%5Ctimes%2010%5E3%5C%20L)
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](https://tex.z-dn.net/?f=d%3D%5Cdfrac%7B374%5C%20g%7D%7B2.2%5Ctimes%2010%5E3%5C%20L%7D%5C%5C%5C%5C%3D0.17%5C%20g%2FL)
So, the density of helium in the balloon is 0.17 g/L.

Start the carbon count at the end closest to the most important element, the double bond. I would recommend drawing the skeletal structure too so you can see where carbons are attached and how long the chain is.
