Question

How many atoms are in a drop of mercury that has a diameter (d) of 1.0 mm? Use: 1 cm = 10 mm (exact) Volume of a sphere is 4/3?r³ where r is the radius and r = 1/2d Density of mercury = 13.6 g/cm³ Relative atomic mass of mercury = 200.59 g/mol One mole of anything = 6.022 x 10²³ units of that thing 6.0 x 10²³ 2.1 x 10¹? 1.7 x 10²? 1.7 x 10²³ 2.1 x 10²²

          How many atoms are in a drop of mercury that has a diameter (d) of 1.0 mm?

Use:
1 cm = 10 mm (exact)
Volume of a sphere is 4/3?r³ where r is the radius and r = 1/2d
Density of mercury = 13.6 g/cm³
Relative atomic mass of mercury = 200.59 g/mol
One mole of anything = 6.022 x 10²³ units of that thing

6.0 x 10²³
2.1 x 10¹?
1.7 x 10²?
1.7 x 10²³
2.1 x 10²²
