1.5% Demecarium bromide Sodium chloride qs Purified water qs 30 mL Make isotonic solution. How many milligrams of sodium chloride is needed to make the solution isbtonic with lacrimal fluids? (Demecarium bromide: m.w. 717; E-value 0.12]. A. 180 mg B. 450 mg ° C. 216 mg D. 90 mg
Isotonic sodium chloride solution contains 0.9% w/v sodium chloride. If the E-value of boric acid is 0.52, calculate the percentage strength (w/v) of an isotonic solution of boric acid.
A prescription reads as follows: Rx Pilocarpine Nitrate 0.3 g Boric Acid Solution q.s. ad 30 mL Make isoton. Sol. Sig: Apply to eyes as directed. Boric acid has an E-value of 0.52. Pilocarpine Nitrate has an E-value of 0.22 How many milliliters of a 5% stock solution of boric acid is needed to fill this prescription. How is this worked out?
How many milliliters each of purified water and an isotonic sodium chloride solution should be used to prepare 30 mL of a 1% w/v isotonic solution of fentanyl citrate (E= 0.11)? Separate each volume by a comma. I need help with this problem. Can you please show me step by step on how to solve this. Thank you.
