A kilogram of silver contains 5.58×10²⁴ atoms.
<h3>How to determine the parameter</h3>
From the question given above, the following data were obtained:
- 1 mole of silver = 107.9 g
- Number of atoms in 1 mole of silver = 6.02×10²³ atoms.
- Number of atoms in a kilogram of silver is unknown
Now, we shall convert 1 kg of silver to grams (g).
This can be obtained as follow:
1 kg = 1000g
Therefore, 1 kg of silver is equivalent to 1000g.
Now, let's determine the number of atoms in 1 kg (i.e 1000 g) of silver as follow:
If 107.9 g of silver contains 6.02×10²³ atoms.
Then, 1000 g of silver will contain:
= (1000 × 6.02×10²³) / 107.9
= 5.58×10²⁴ atoms.
Thus, a kilogram of silver contains 5.58×10²⁴ atoms.

Answer:
B) 28x + 9
Step-by-step explanation:
The definition of the perimeter of a closed figure is the total distance around the edge of an enclosed figure.
You can obtain the perimeter of polygons by simply adding up all of the sides of the polygon.
Since all of the sides values are given to you, you can write the expression:
6x + 1 + 5x - 3 + 6x + 1 + 11x + 10 in order to represent the perimeter.
This equals to 28x + 9
