If a cough syrup contains 0.24gm of codeine in 120ml, how many mg are contained in each teaspoonful?
"teaspoonful" is not a metric unit of measurement.
One has to know how many ml are in a teaspoonful
Once you have looked that up, set up a ratio.
24g/120 ml = x g/"teaspoonful" ml
cross-multiply and solve for x
so one teaspoon = 5ml
my answer is 1gr?
.24g/120 ml = x g/"teaspoonful" ml, sorry I dropped the decimal in front of 24 g
....
x = .01 g
I leave it up to you to convert .01 g to mg.
A physician precribes tetracycline suspension for a patient who is to take 2 teaspoofuls four times a day for 4 days, then 1 teaspoonful four times a day for 2 days. How many mls of the suspension should be dispensed?
To find the amount of codeine in each teaspoonful, we need to convert the given amount in grams to milligrams and then divide it by the volume of each teaspoonful.
First, we convert the amount of codeine from grams to milligrams. Since there are 1,000 milligrams in 1 gram, we multiply 0.24 grams by 1,000:
0.24 grams * 1,000 = 240 milligrams
Now we know that there are 240 milligrams of codeine in 120 milliliters (ml) of cough syrup.
To find how many milligrams are contained in each teaspoonful, we need to know the volume of a teaspoon. A standard teaspoon is generally considered to be 5 milliliters. So, we can set up a proportion:
240 milligrams / 120 milliliters = x milligrams / 5 milliliters
Cross-multiplying and solving for x, we get:
240 milligrams * 5 milliliters = 120 milliliters * x milligrams
1,200 milligram-milliliters = 120 milliliters * x milligrams
1,200 milligram-milliliters / 120 milliliters = x milligrams
x = 10 milligrams
Therefore, each teaspoonful of the cough syrup contains 10 milligrams of codeine.
