Answer:
0.11 M
Explanation:
The computation of molarity of the CH3COOH solution is shown below:-
Where,
= Molarity of LioH = 0.0175
= Volume of LioH = 18.5 ml
= Volume of CH3COOH = 29.4 ml
Now, we will put the values into the formula
Which gives result
= 0.011 M
Therefore for computing the molarity of the CH3COOH solution we simply applied the above formula.
To get the number of gold atoms, you have to divide the mass of the gold by the mass of the gold atom. It follows this simple equation 
.
Let x be the number of gold atoms. Plug in the values to a calculator.
x =
Both have the same units so the unit gram(g) can be cancelled.
x then would be equal to 1.53x10^22. So there are 1.53x10^22 atoms of gold in 5 g of gold
