Interpretation:
Pathway for finding “moles of B” from “grams of A” using the conversion factors has to be chosen from the given options.
Concept Introduction:
Using the
Molar mass of a substance gives a relationship between the number of grams and number of moles of that particular substance.
The Chemical formula subscript also provides relationship between the number of moles of substance to the number of moles of its individual components present in the substance.
The moles of compound are related to moles of another compound by the coefficients present in the balanced chemical equation.
All the above relationship can be put into a single diagram as shown below,

Cheersarrow_forwardYou have an order for 1 gram of Cefazolin in D5W 100 ml. You have added 5 ml of sterile water to the 1 gram vial to reconstitute powder. However the recommended manufacturer’s diluent amount is 10 ml of sterile water for a final concentration of 100 mg/ml. How would reconstituting the vial with 5 mls affect the concentration and the final calculated dose. Please answer with explanation ASAP. I will really upvote. Thanksarrow_forward
