How many atoms are contained in 100.0 g of mercury

Sagot :

3.00097 x [tex]10^{23}[/tex] 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 = [tex]\frac{mass}{molar \;mass}[/tex]

Number of moles of mercury = [tex]\frac{100.0 g}{200.59 u}[/tex]

=  0.4985 moles

Number of moles of mercury = Number of atoms = moles of Hg x [tex]6.02 X 10^{23}[/tex]

= 0.4985 x [tex]6.02 X 10^{23}[/tex]

= 3.00097 x [tex]10^{23}[/tex] atoms.

Hence, 3.00097 x [tex]10^{23}[/tex] atoms are contained in 100.0 g of mercury.
