Answer:

162 mL  

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

V = \text{2 fl oz} \times \dfrac{\text{29.57 mL}}{\text{1 fl oz}} = \textbf{59 mL}

(c) Banana flavouring

V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.928 mL}}{\text{1 tsp}} = \textbf{2.5 mL}

2.Calculate the total volume

Chlorpheniramine =  100  mL

Lidocaine               =   59

Banana flavouring = <u>    2.5  </u>    

TOTAL                    = 162 mL
