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.
B is the answer. For an equation to be balanced there must be the same amount of each element on the two sides. The only one where this is the case is B.
