A children's liquid cold medicine has a specific gravity of 1.23. If a child is to take 1.5 tsp in a dose, what is the mass (in
julia-pushkina [17]

Assume 1 tsp is approximately can hold 5 mL liquid.

Given the dose of medicine = 1.5 tsp

Converting 1.5 tsp to mL:

1.5 tsp * \frac{5 mL}{1 tsp} = 7.5 mL

Given the specific gravity of the medicine = 1.23

That means density of the medicine with respect to water will be 1.23

As the density of water is 1 g/mL

We can take density of the medicine to be 1.23 g/mL

Calculating the mass of medicine in grams:

7.5 mL * \frac{1.23 g}{mL} =9.225 g

9.225 g medicine is present in one dose.
