Answer:
50,000 tablets may be prepared from 30g of colchicine
Step-by-step explanation:
This problem can be solved as a rule of three problem.
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.
Unit conversion problems, like this one, is an example of a direct relationship between measures.
First Step:
The first step is knowing how many g are in a tablet.
Each gram has 1,000,000 mcg. So:
1g - 1,000,000 mcg
xg - 600 mcg
1,000,000x = 600
Each tablet has 0.0006g
Final step:
How many tablets may be prepared from 30g of colchicine?
1 tablet - 0.0006g
x tablets - 30g
0.0006x = 30
x = 50,000
50,000 tablets may be prepared from 30g of colchicine
