Question

How many 100 mg tablets will you need to make 1/2 liter of a 1:250 solution?

Answer 1

To make a 1:250 solution in Chemistry, you will need 2 tablets of 100 mg each to make 1/2 liter of the solution.

Step-by-step explanation:

To make a 1:250 solution, you need to know the amount of solute (in this case, 100 mg tablets) and the final volume of the solution (1/2 liter or 500 mL).

First, convert the volume to milliliters:

1/2 liter = 500 mL

Next, determine the concentration ratio:

1:250 = 1 part solute to 250 parts solvent

Finally, calculate the number of tablets needed:

Number of tablets = (500 mL/250) * 100 mg

Therefore, you will need 200 mg tablets or 2 tablets to make 1/2 liter of a 1:250 solution.
