Question

I've shown the work I have done, but I'm not super confident in my answers. If you could let me know if they are right/wrong, and help me solve anything I got wrong, I'd so appreciate it! 4. Prepare the following solutions: A. 250 mL of a 3.3 M KCI (Mw 74.6 g/mo) internal solution: B. 1000 uL of a 0.5 mM NaoH (MW 40 g/mol solution 2x10 NaoH C. How many grams of sucrose (Mw 342.3 g/mol) would you dissolved in 750 mL to get a 796 solution? D. How many grams will you need to make a 1 Lof 0.5 M solution of a drug (MW a 70 mmol)?

Explanation / Answer

A) correct

B) correct

C) w/v % = 7 %

w/v% = weight of solute x 100 / volume of solution

7 = weight of sucrose x 100 / 750

weight = 52.5 g

sucrose needed = 52.5 g

D) correct
