Step 1
Given;
[tex]\begin{gathered} \text{Volume of sea water = 30ml} \\ \text{Percentage of oxygen= 85.84\%} \end{gathered}[/tex]
Required; To find how many ml of oxygen are in the sample?
Step 2
Calculate how many ml of oxygen are in the sample
[tex]=\frac{\text{percentage of oxygen in sample}}{100}\times30[/tex][tex]=\frac{85.84}{100}\times30=25.752ml[/tex]
Hence, there are 25.752ml of oxygen in the sample of seawater.
