Question

5.How much of a 30% solution would you need to make 50 mL of a 2% solution?

Answer 1

The quantity of a 30% solution you would need to make 50 mL of a 2% solution is;

`3.33\text{ mL}`

Step-by-step explanation:

Let x represent the quantity of a 30% solution you would need to make 50 mL of a 2% solution.

`\begin{gathered} 30\text{\% of }x=2\text{\% of 50 mL} \\ 0.3* x=0.02*50\text{ mL} \\ x=\frac{0.02*50\text{ mL}}{0.3} \\ x=3.33\text{ mL} \end{gathered}`

Therefore, the quantity of a 30% solution you would need to make 50 mL of a 2% solution is;

`3.33\text{ mL}`
