So if I told you there are 5 ml's per teaspoon and there are 100 mg guaifenesin and 10 mg dextromethorpan in a solution of 5ml, you couldn't tell me how many teaspoons there would be?

Right. So how many mg of guaifenesin and dextromethorpan in one teaspoon?

To get your answer to the second question: since there are three teaspoons in a tablespoon, multiply your answer to this question by 3.

100mg guaifenesin and 10 mg of dextro are present in 1 teaspoon.

300 mg guaifenesin and 10 mg of dextro in 1 tablespoon?

Almost. The first part is right. The second part should be 300/30. Multiply everything by 3.

Question 1: So you know you have 100mg/10mg in 5 ml. There are 5ml in one teaspoon so naturally you have 100mg/10mg in one teaspoon.

Question 2: There are three teaspoons in a table spoon. So multiply the 100mg/10mg (in each teaspoon) x 3 = 300mg guaifenesin and 30 mg dextro.

Assuming the questions read:

"How much guaifenesin & dextromethorpan are in one teaspoon?"

"How much guaifenesin & dextromethorpan are in one tablespoon?"

Then yes. It's that simple. I'm guessing you waaaay overthought this one.

If I'm wrong then I'm just going to ban myself from here from now on.
