Answer: The number of moles of the weak acid in the solution is 0.00396
Explanation:
To calculate the number of moles for given molarity, we use the equation:
a)
The balanced chemical reaction is:
1 mole of base uses = 1 mole of
0.00396 moles of base use =
moles of
Thus the number of moles of the weak acid in the solution is 0.00396
Answer:
1 1
5 2
6 1
8 3
10 3
6 3
9 3
13 3
Explanation:
First of you add the subscripts (the little numbers after the letters) and multiply the big numbers before the letters together to get the number of atoms
For Example:
O= 1 atom
Si{2}= 2 atoms
Mg{5}C{6}= 11 atoms
3Na{2}= 6 atoms
O(SiNa){2}= OSi{2}Na{2}= 5 atoms
Each Capital letter is a new Element
For Example:
O = 1 Element
NaSi = 2 Elements
Answer: option C. Sulphur
