If the patient has to take 2 tablets every 8 hours for 7 days.
24/8=3 3*2=6
this means that he patient will have to take 6 tablets every day.
6*7=42 And the patient must take 42 tablets in all 7 days
Hope this helps! :)

Answer:
the answer is 0
Explanation:
love the profile pic by the way
FeBr3(aq) + NaOH(aq) = FeOH(s) + NaBr3(aq)
The question above can be answered by using the volume balance concept. Two equations can be established by total volume balance and the component (acid) volume balance.
If we let x be the volume of the 12% acid solution, the volume of the 20% acid solution will have to be 100 - x.
x + (100 - x) = 100
Then, the acid mass balance will give us the equation,
(x)(0.12) + (100 - x)(0.20) = (100)(0.18)
Simplifying,
0.12x + 20 - 0.20x = 18
-0.08x = 20 - 18
-0.08x = 2
The value of x from the equation is 25.
<em>Hence, the volume of the 12% acid solution is 20 galloons and that of the 20% acid solution is 75 galloons. </em>
