Question

How do you calculate the number of grams in 0.0043 moles?

Answer 1

We can tell you the number of particles; we cannot tell you the number of grams.

Explanation:

`0.0043` `mol` represents the number of a given particle; i.e. `4.30xx10^(-2)*mol xx N_A` particles, where `N_A=6.022xx10^23*mol^-1`. `N_A` is the link between the micro world of atoms and molecules to the macro world of grams, and kilograms, and litres. How?

Well, it turns out that `N_A` `""^12C" atoms"` have a mass of `12*g` precisely. And thus the mole is the link between the micro world of atoms and the macro world of grams and kilograms. You have to tell us of what material you have the `0.0043` `mol`.
