How plentiful milligrams of clobetasol are contained contained by 15g of clobetasol oil 0.05%w/w?
Answer:
If you mean 15ml, afterwards the answer is 7.5mg.
100% = 1g
1% = 10mg
0.05% = 0.5mg
erm..15000mg
1000mg =1g
15g = 15000mg
Why the question?
see this http://www.nlm.nih.gov/medlineplus/drugi...
75mg.
.05% is 1/2000 of 100%
75mg is 1/2000 of 15g.
Since the expediency was given within w/w, let's try using that approach.
So, If 100g of clobetasol contains 0.05g
then 15g = 15/100 x 0.05g
= 0.75/100
= 7.5 x 10 ^ -03g
but 1g = 1000mg
there4 7.5 x 10 ^ -03g = (7.5 x 10 ^ -03) x 1000
= 7.5mg
hence, 7.5mg of clobetasol are contained contained by 15g of clobetasol ointment.
0.05%w/w channel 0.05grams per 100grams
Using ratio and proportion,
0.05/100 = x/15
x = 0.0075g
Convert this to milligrams using 1000mg = 1g
Therefore,
0.0075g x 1000mg/1g = 7.5mg
ANSWER: 7.5milligrams clobetasol
