dimensional analysis need to learn the steps in solving this problem

Answer 1

1. Using dimensional analysis required ml of Epinephrine as per order

=0.15 mg/ 1 X 1 ml/ 1 mg

= 0.15 ml

2. Using dimensional analysis required ml of atropine as per order

=600 mcg/1 X 1 ml/ 400 mcg (here 1 mg = 1000 mcg)

= 1.5 ml

3. Using dimensional analysis required ml of Cogentine in ml

= 1.5/1 X 2 ml/ 2mg

= 1.5 ml
