I would personally convert the 12 mg to g so I could see what I was working with. So 12 mg to grams is 0.012 g...
so 1 tablet is 0.012g. the patient needs 0.024 g.
so 0.024g/0.012g = 2 tablets or 0.012g X 2 is 0.024 g
hope this helps :)
Answer:
D
Explanation:
Because the silk took away the electrons to allow the rod to become positive. They cant be destroyed because of the law of conservation of charges. Also protons cannot move only electrons can.
0.424209104545485 is the answer my friend lol or at least what I got
- See charge on ion is -1 .
Hence it has taken 1 electron
Now first look at EC of Fluorine(F)
![\\ \bull\sf\dashrightarrow 1s^22s^22p^5](https://tex.z-dn.net/?f=%5C%5C%20%5Cbull%5Csf%5Cdashrightarrow%201s%5E22s%5E22p%5E5)
- Now one electron added .hence no of electrons is 10now
Look at the EC
![\\ \bull\sf\dashrightarrow 1s^22s^22p^6](https://tex.z-dn.net/?f=%5C%5C%20%5Cbull%5Csf%5Cdashrightarrow%201s%5E22s%5E22p%5E6)
Or
![\\ \bull\sf\dashrightarrow [He]](https://tex.z-dn.net/?f=%5C%5C%20%5Cbull%5Csf%5Cdashrightarrow%20%5BHe%5D)
Option C is correct.
