Question

Calculate the no of gram atom (moles)in 0.1g of sodium.

Answer 1

Answer:

The no of gram atom (moles)in 0.1g of sodium is 0.0043

Explanation:

Atomic mass of sodium = 23

the number of gram atoms / moles =  $\frac{weight}{atomic weight}$

here weight = 0.1g

atomic weight = 23

∴no of gram atoms in 0.1g of sodium is = $\frac{0.1}{23}$ = 0.0043 moles

The no of gram atom (moles)in 0.1g of sodium is 0.0043
