Answer:
162 mL
Step-by-step explanation:
1.Convert all volumes to millilitres
(a) Chlorpheniramine
V = 100 mL
(b) Lidocaine
(c) Banana flavouring
2.Calculate the total volume
Chlorpheniramine = 100 mL
Lidocaine = 59
Banana flavouring = <u> 2.5 </u>
TOTAL = 162 mL
Should be C
Only the same power number can be use to add or subtract :)
But why is A, B and C same kinda stuff?
Question 20 3 < c < 9
Question 21 2.5
