Hi everyone,
I am practicing the very popular 120 SDN calculations, some of the answers/solutions provided seem not to be accurate to me. I was wondering if other students out there wanna discus or even post their own solutions. Any feedback is welcome!
Problem 12:
How many ml of the Dextrose 70% in Water Injection will you add to the sterile water?
The sterile water volume is 1000ml and I don't think we should use 1015ml - anyhow that is not the main error.
Here is my solution: Please compare to the one provided and give me your feedback
10%
10g in 100ml
X? in 1000ml
X= 100g is needed
We have the 70% Dextrose
70g in 100ml
100g in Y?
Y= 142.8 ml of 70% Dextrose
Alternative 1:
70% * Y? = 10% * 1000
Y= 142.8 ml of 70% Dextrose
Alternative 2: Alligation
70% 10 parts
10%
0% 60 parts
TOTAL PARTS 70 not 60
10 parts of 70 parts D70%
Y? 1000 ml
Y= 142.85 ml
