Answer:
a. 10.0 g
Explanation:
The molar mass of NaOH is 39.997 grams which was calculated by adding the molar mass of Sodium, Oxygen, and Hydrogen 
. But before we do anything with this number we must first convert 
molecules to moles. We can do this by dividing by Avogadro's number or 
( 
moles). We then convert moles to grams by multiplying by the molar mass of NaOH, (
grams). This is almost exactly 10 and the margin of error is likely due to the original numbers not being precise enough.
2. Left to right (smallest to largest) F-, Mg2+, Na+, and K+
5. Cs, Ga, As, N, O
6. Cs or H (probably cesium)
7. In or In 2+ (not sure which)
Hope this helps, I've never really seen questions like this before.
