Question

How many mercury atoms are in 6.7 mol of mercury?

Answer 1

i think there are 13.55 g/c.c

Answer 2

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.
