Answer:
10.35%
Explanation:
Find the molar mass of water, using your periodic table: 18.02 g. Then find the molar mass of the total substance: 174.10 g.
Divide the molar mass of water by the molar mass of the total substance and multiply 100%. Doing this, you get 10.35%.
2.5; if the patient needs 625 mg and each pill is 250 mg- they would need take 2 for 500 mg and then cut one in half to add the extra 125 mg for 625 mg. or: (2)250+(1/2)250=625
Hope this helps!
