Question

Calculate the density of helium if a balloon with a capacity of 5.00 L holds 0.890 g.

Answer 1

Answer:

Explanation:

Density is m/V. Also, 1 liter = 1000 $cm^3$. So, we get 0.890/(5*1000) = $1.78*10^{-4}$ g/cm^3. You can convert this to kg/m^3 as well by multiplying it by 10. Depends which one you want.
