Answer:
powder volume = 250mg/ml * 78ml = 19,500mg = 19.5grams
Explanation:
A 150 ml bottle of Amoxicillin
250 mg/ml for oral suspension of Amoxicillin
requires the addition of 78 ml of Purified Water
to give a 150 ml of suspension.
given that the dosage of powder amoxicillin is 250mg to 1ml of water
therefore for 78ml of water;
the powder volume =suspension/water
= 250mg/ml * 78ml = 19,500mg = 19.5grams
Answer:
d. The pH of the beaker`s contents will decrease.
Explanation:
Since the new substance is an acid and has a very low pH, that is 1. it will reduce a little bit the pH of the original base (NaOH). Some ions of hydrogen of the acid are going to react with the hydroxyl group of the sodium hydroxide to form water.
Since the differences of the volume is big, only a small part of the base is going to be neutralize, but at the end, the final pH of the solution is still going to be a base.
Hope this information is useful.
