Question

How many atoms are contained in 100.0 g of mercury

Answer 1

3.00097 x $10^{23}$ atoms are contained in 100.0 g of mercury.

What is moles?

The mole is defined as the amount of substance that contains as many elementary entities as there are atoms in exactly 12 g of carbon-12.”

Number of moles of mercury = $\frac{mass}{molar \;mass}$

Number of moles of mercury = $\frac{100.0 g}{200.59 u}$

=  0.4985 moles

Number of moles of mercury = Number of atoms = moles of Hg x $6.02 X 10^{23}$

= 0.4985 x $6.02 X 10^{23}$

= 3.00097 x $10^{23}$ atoms.

Hence, 3.00097 x $10^{23}$ atoms are contained in 100.0 g of mercury.
