Step 1

Given;


\begin{gathered} \text{Volume of sea water = 30ml} \\ \text{Percentage of oxygen= 85.84\%} \end{gathered}

Required; To find how many ml of oxygen are in the sample?

Step 2

Calculate how many ml of oxygen are in the sample


=\frac{\text{percentage of oxygen in sample}}{100}*30
=(85.84)/(100)*30=25.752ml

Hence, there are 25.752ml of oxygen in the sample of seawater.
