Please help me :( How many atoms are present in 179.0 g of iridium?

A. 6.464x10
B. 1.157x10
C. 5696x10
D. 1078 x 10

There are atoms present in 179.0 g of iridium.

Explanation:

Given: Mass = 179.0 g

Moles is the mass of a substance divided by its molar mass. So, moles of iridium (molar mass = 192.217 g/mol) is as follows.

According to the mole concept, 1 mole of every substance contains atoms.

Therefore, atoms present in 0.931 moles are calculated as follows.

Thus, we can conclude that there are atoms present in 179.0 g of iridium.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
