How many silver atoms are there in 3.78g of silver?
oksian1 [2.3K]

2.1 x 10²²atoms

Explanation:

Given parameters:

Mass of silver = 3.78g

Unknown:

Number of atoms of silver = ?

Solution:

To solve this problem, we first find the number of moles of the silver from the given mass.

  Number of moles = \frac{Mass}{Molar mass}

Molar mass of Ag  = 108g/mole

   Number of moles = \frac{3.78}{108}  = 0.035mole

Now;

  A mole of any substance contains 6.02 x 10²³ atoms

     0.035 moles of Ag will contain 0.035 x 6.02 x 10²³ = 2.1 x 10²²atoms

how does resistance change with temperature? is there more resistance or less resistance at higher temperatures?
timofeeve [1]

The resistance has a linear relationship with temperature because it increases as temperatures increases.

<h3>What is temperature?</h3>

Temperature refers to the activity (motion or thermal energy) in the atoms that form molecules.

The resistance of an electric conductor increases as the temperature increases since the thermal energy of subatomic electrons also increases.

In conclusion, the resistance has a linear relationship with temperature because it increases as temperatures increases.
