Answer:
8/27 of hydrogen peroxide from the stock bottle
Explanation:
• The amount of hydrogen peroxide retrieved by James = 2/3
,• The amount the pharmacist instructs James to retrieve = 4/9 times 2/3
This gives the expression:
[tex]\frac{2}{3}\times\frac{4}{9}[/tex]Multiply the numerators and the denominators.
[tex]\begin{gathered} =\frac{2\times4}{3\times9} \\ =\frac{8}{27} \end{gathered}[/tex]Observe that the result cannot be simplified further.
Thus, James needs 8/27 of hydrogen peroxide from the stock bottle to prepare the bulk compound.
