Calculate the number of sodium atoms in 0.1 grams of sodium?

Answer:

The number of Sodium atoms in 0.1g of Na is equal to 2.62×10²¹ atoms.

Explanation:

23g of sodium contains no. of atoms =$6.023*10^{23}$

0.1g of Na contains atoms  $=(\frac{ 6.023*10^{23} }{23} )(0.1)$

                                                    $=2.62*10^{21}$ atoms

Therefore, no. of Na  atoms present in 0.1 gram sodium is 2.62×10²¹ atoms.
