Question

The physician ordered 3/4-strength Isocal. The total volume is 100 mL. How many milliliters of water need to be mixed with Isocal?

Answer 1

To achieve a
`3/4-strength` Isocal solution with a total volume of
`100 mL` ,
`25 mL` of water must be mixed with
`75 mL` of Isocal.

Step-by-step explanation:

To determine how many milliliters of water need to be mixed with Isocal to achieve a
`3/4-strength` solution with a total volume of
`100 mL` we can apply the concept of dilution. A
`3/4-strength` solution means that 3 parts of the total volume will be Isocal, and 1 part will be water.

Since the total volume is
`100 mL` we divvy that into
`4` equal parts (representing the 3/4 strength and the water portion). Each part is

`100 mL / 4 = 25 mL`.

Therefore for a
`3/4-strength` solution, we would use 3 parts Isocal
`(3 × 25 mL = 75 mL)` and 1 part water
`(1 × 25 mL = 25 mL)`. Thus
`25 mL` of water needs to be mixed with
`75 mL` of Isocal to make a total of
`100 mL of 3/4-strength` Isocal solution.
