The given question is :
480 mg of oxygen is dissolved in the water of a 60 L aquarium. What is the concentration of dissolved oxygen?
Given:
Mass of oxygen = 48 mg
48 mg of oxygen is dissolved in the water of a 60 L aquarium
To find,
The concentration of dissolved oxygen.
Solution,
concentration of dissolved oxygen = (mass of water/mass of solution)×100
48 mg = 0.000048 L
[tex]=\dfrac{0.000048}{0.000048+60}\times 100\\\\=7.99\times 10^{-5}[/tex]
So, this is the required solution.
