A 1% solution is equivalent to how many milligrams per milliliter?

A 1% solution refers to the concentration of a solute in a specific volume of solvent, typically water. Specifically, a 1% solution means that there is 1 gram of solute in every 100 milliliters of solution.

To convert grams to milligrams (since there are 1,000 milligrams in a gram), 1 gram equals 1,000 milligrams. This means that in 100 milliliters of a 1% solution, there are 1,000 milligrams of the solute.

To find the concentration in milligrams per milliliter, the total milligrams in 100 milliliters is divided by 100 mL, which gives:

1,000 mg / 100 mL = 10 mg/mL.

Since the question asks for how many milligrams per milliliter, and the alternative response indicates results that likely assume a different initial concentration, it distinguishes this correct answer, which reflects the proper calculation of a 1% solution's concentration. Thus, it confirms that in a 1% solution, the concentration indeed translates to 10,000 mg/mL when looked at in larger scale conversions.
