Final answer:

To find the required amount of Theophylline elixir for a 120mg dose, calculate the volume based on the elixir's concentration and convert the result from milliliters to tablespoons. The correct dose is 1.5 tablespoons.

Explanation:

To calculate the amount of the Theophylline elixir required for a dose of 120mg, we need to set up a proportion since the concentration of the elixir is given as 80mg/15ml. We use the following equation to find the volume needed:

Dose required (mg) / Concentration (mg/ml) = Volume required (ml)

First, we need to find the concentration in mg per ml:

80 mg / 15 ml = 5.33 mg/ml

Then, we use the required dose to find the volume:

120 mg / 5.33 mg/ml = 22.5 ml

Finally, we convert the volume in milliliters to tablespoons using the conversion that 1 tablespoon is approximately 15 ml:

22.5 ml / 15 ml/tbsp = 1.5 tbsp

Therefore, the correct amount of elixir required is 1.5 tablespoons.
