Final answer:
To provide a 1 gram dose of Amoxicillin 250mg/5ml, you would need 20 ml of the medicine. This is calculated using a simple proportion based on the given concentration of Amoxicillin.
Step-by-step explanation:
The student is asking how many milliliters (ml) of Amoxicillin 250mg/5ml are required to provide a 1 gram dose. Since there are 1000 milligrams in a gram, the student needs to convert 1 gram to milligrams, which is 1000mg. To calculate the amount of liquid required, use the given concentration of the medicine.
The concentration of the Amoxicillin is 250mg per 5ml. So, for every 250mg, 5ml is required. To find out how much liquid is needed for 1000mg, set up a proportion: 250mg is to 5ml as 1000mg is to X ml.
Using the formula:
250mg / 5ml = 1000mg / X ml
Cross-multiply to solve for X:
250mg * X ml = 5ml * 1000mg
Which simplifies to:
250X = 5000
Dividing both sides by 250 gives:
X = 5000 / 250
X = 20 ml
Therefore, you would need 20 ml of the Amoxicillin suspension to provide a 1 gram dose.
