Answer:

33 mL  

Explanation:

It is important to recognize that the total amount of pure syrup remains constant:

Total syrup in the stock solution = total syrup in dilute solution

Thus, we can use the dilution formula

V₁c₁ = V₂ c₂

Data:

V₁ = ?;          c₁ = 80 %  

V₂ = 47 mL; c₂ = 24 %

Calculations:

1. The volume of stock syrup

\begin{array}{rcl}V_{1}c_{1} & = & V_{2}c_{2}\\V_{1}\times80 \, \% & = & \text{47 mL}\times 24 \, \%\\80V_{1} & = & \text{1130 mL}\\V_{2}&=& \dfrac{\text{1130 mL}}{80}\\\\&=&\text{14 mL}\\\end{array}\\\text{You need $\textbf{14 mL}$ of stock syrup.}

2.  The volume of soda solution

Total volume of dilute solution =  47 mL

The volume of stock syrup        =  <u>14 </u>

Volume of soda solution            = 33 mL

You need 33 mL of soda solution.

The living will is a document whose precise purpose is to allow individuals to record specific instructions about the type of healthcare they would like to receive in particular end-of-life situations.
An advance directive, commonly referred to as a living will, is a legal instrument that describes the kind of medical care a person wants or does not want in the event that they are unable to express their preferences verbally. Doctors and hospitals refer to the living will when a patient is asleep and has a terminal illness or a life-threatening accident to determine whether the patient wants life-sustaining treatment, such as aided breathing or tube feeding. In the absence of a living will, the spouse, family members, or other third parties are in charge of making decisions on medical treatment.
