Answer:
4.0* 10^(24) mercury atoms

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number
6.023* 10^(23) of particles.

1 mole of mercury
Hg contains=
6.022* 10^(23) atoms

Thus 6.7 moles of mercury
Hg contains=
(6.022* 10^(23))/(1)* 6.7=4.0* 10^(24) atoms

Thus there are
4.0* 10^(24) mercury atoms are in 6.7 mol of mercury.
