How many atoms are contained in 100.0 g of mercury
Romashka [77]

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

<h3>What is moles?</h3>

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.
