To prepare 30 mL of a 1% isotonic solution of procaine hydrochloride (E = 0. 21), how many grams of NaCl is needed? (by E value method)
Added by Jordi S.
Step 1
We need to prepare 30 mL of a 1% isotonic solution of procaine hydrochloride. The E value for procaine hydrochloride is given as 0.21. The E value represents the amount of NaCl equivalent in osmotic activity to 1 g of the drug. We need to calculate how much NaCl Show more…
