Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the number of silver atoms in 330 grams of a silver bracelet by knowing 1 mole of silver has a mass of 108 grams and also contains 6.022x10²³ atoms; thus, the mathematical setup is shown below:
Which is equal to:

Calculate the normality of 1 Kg of aluminum sulfide in 5000 ml of solution.
Normality comes out to be 8.11
<h3> Given </h3>- Mass of solute: 1000g
- Volume of solution (V): 5000 ml = 5 liters
- Equivalent mass of solute (E) = molar mass / n-factor
n-factor for is 6 and molar mass is 148g
So, on calculating equivalent mass is equal to 24.66g
FORMULAE of Normality (N) = (Mass of the solute) / (Equivalent mass of the solute (E) × Volume of the solution (V)
N=
<u> N=8.11</u>
Therefore, normality of 1 kg aluminum sulfide is 8.11
