Question

Molar Volume of Sodium
If you assume that an atom is a hard sphere, you can estimate the average volume of space it occupies using basic geometry.

Question

Estimate the volume, V , of a sodium atom ( Na ) using its metallic radius of 186

Answer 1

Isn't the volume of a sphere
4/3(pi)r³?

Answer 2

yes it is .. can u slove it plz

Answer 3

186 what units? What units do you want the answer?
(4/3)*3.14*186³ = ??

Answer 4

If you assume that an atom is a hard sphere, you can estimate the average volume of space it occupies using basic geometry.

Estimate the volume,V , of one sodium atom (Na) using its metallic radius of 186 pm .

Express your answer in cubic picometers.

Answer 5

The molar mass of Na is 22.99g
The density of solid sodium is 0.97g/cm^3
(22.99g/mol) / (0.97g/cm^3) = _____________
What are the units of the above value

Answer 6

Part A: 2.7*10^7
Part B: 16.3
Part C: D
