Answer:
The answer to your question is below
Explanation:
Data
density = 13.53 g/cm³
volume = 62.5 cm³
mass = ?
moles = ?
atoms = ?
Process
1.- Calculate the mass of mercury
formula
density = mass/volume
-Solve for mass
mass = density x volume
-Substitution
mass = 13.53 x 62.5
-Result
mass = 845.63 grams
2.- Calculate the moles of mercury
Atomic mass = 200.6 g
200.6 g of mercury --------------------- 1 mol
845.63 g of mercury -------------------- x
x = (845.63 x 1) / 200.6
x = 4.22 moles of mercury
3.- Calculate the number of atoms
1 mol -------------------- 6 .023 x 10 ²³ atoms
4.22 moles ------------- x
x = (4.22 x 6.023 x 10²³) / 1
x = 2.54 x 10²³ atoms
