Question

Cleocin suspension is available in a concentration of 75 mg/5 ml. how many ml are required for a 300 mg dose?

Answer 1

20ml because 75mg four time equal 300mg and 5ml four times equal 20ml

Answer 2

For a
`300mg` dose
`20ml` are required

Step-by-step explanation:

To solve this problem, we can state that exist a direct linear relationship between the amount of
`mg` and the amount of
`ml`

We can write the following rule of three and find the value of ''
`x`'' :

`(75mg)/(5ml)=(300mg)/(x)` ⇒

`x=((300mg).(5ml))/(75mg)`

`x=20ml`

We find that the milliliters required for a
`300mg` dose are
`20ml`
