Calculate (a) the number of milligrams of metoclopramide HCl in each milliliter of the prescription:Metoclopramide HCl 10 gMethylparaben 50 mgPropylparaben 20 mgNaCl 800 mgPurifed water qs ad 100 mL

Answer:There are 100 milligrams of metoclopramide HCl in each milliliter of the prescriptionStep-by-step explanation:When the prescription says Purified water qs ad 100 mL means that if we were to make this, we should add the quantities given and then, fill it up with water until we have 100 mL of solution, being the key words qs ad, meaning sufficient quantity to get the amount of mixture given.Then, knowing there is 10 grams of metoclopramide HCl per 100 mL of prescription, that means there is (1 gram = 1000 milligrams) 10000 milligrams of metoclopramide HCl per 100 mL of prescription. That is a concentration given in a mass/volume way.Knowing the concentration, we can calculate it per mL instead of per 100 mL[tex]Concentration_{metoclopramide HCL}= \frac{10000mg}{100mL} =100 \frac{mg}{mL}[/tex]
