Question

A suspension contains 250 mg per 5 ml of drug. how many milligrams are contained in 1 oz of suspension?

Answer 1

Answer:
1500 mg per ounce.

Step-by-step explanation:
To find this value we must see how many milligrams are in an ounce and use that ratio to find how much of a drug is in an ounce.
30 mL is equal to an ounce, therefore:
250 mg/5 mL =
`(x)/(30)` mL.
Cross multiply the numerators and the denominator.
7500=5x.
Divide both sides by 5
x =1500.

The answer is 1500 mg per ounce.

Answer 2

Answer:
amount present in 1 oz = 1478.67648 mg

Step-by-step explanation:
First, we will need to convert oz to ml:
1 oz is equivalent to 29.5735296 ml

Now, we can solve our problem.
We are given that there are 250 mg per 5 ml of drug. To get the amount of mg in 29.5735296 ml of drug, all we need to do is cross multiplication as follows:
250 mg ................> 5 ml
?? mg ................> 29.5735296 ml

amount =
`(29.5735296*250)/(5) = 1478.67648 mg`

Hope this helps :)
