3 tbsp. of extract are mixed with 250 ml. of oral suspension base. What is the final concentration of the suspension?

I request the proper formula to figure out how to work this problem. Thank you.

3 tbsp =3*15 ml = 45 ml.

250 ml base
Total volume = 250+45 ml = 295 ml.
Concentration
=45 ml / 295 ml
= 15% approx.

(note: 1 tsp=5ml, 1 tbsp=15ml)

To calculate the final concentration of the suspension, you can use the formula:

Final concentration = Amount of extract / Total volume of suspension

In your case, the amount of extract is given as 3 tbsp. To convert tablespoons (tbsp) to milliliters (ml), you need to know the conversion factor. One common conversion is that 1 tablespoon is equal to approximately 14.79 ml.

So, 3 tbsp is approximately 3 × 14.79 = 44.37 ml.

The total volume of the suspension is given as 250 ml.

Now, you can substitute these values into the formula:

Final concentration = 44.37 ml / 250 ml

Simplifying this gives us:

Final concentration = 0.17748

Therefore, the final concentration of the suspension is approximately 0.17748, or you can round it to 0.18 (rounded to two decimal places).
