How many silver (ag) atoms are in a silver bar that is 20.0 g? a. 1.3 3 1027 ag atoms b. 6.02 3 1023 ag atoms c. 1.1 3 1023 ag atoms d. 1.8 3 1023 ag atoms

The correct option is, (C)

Explanation: Given,

Mass of Ag = 20 g

Molar mass of Ag = 108 g/mole

First we have to calculate the moles of Ag.

Now we have to calculate the number of atoms in Ag.

As, 1 mole of Ag contains number of Ag atoms

So, 0.185 mole of Ag contains number of Ag atoms

Therefore, the number of atoms present in Ag are,

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
