The molecular weight(M) of chalk(CaCO3) = (40+12+48)g/mol =100g/mol
and teaspoon (m)= 4.93g
We know, n=m/M
So, n= (4.93/100) mol = .0493 mol
To find out number of molecules we use, N= n x NA equation.
N= .0493 mol x 6.02 x 1023 molecules/mol
=2.968 x 1022 molecules
Therefore, there are 2.968 x 1022 molecules in a teaspoon of chalk.

How do you calculate number of moles in 1 teaspoon of salt?
First weigh the salt, preferably in grams. To finish the question let pretend it weighed 2g. Next calculate the molar mass of salt (NaCl). Na = 22.98976928 g/mol plus Cl = 35.45 g/mol so NaCl = 58.43976928 g/mol. If 58.43976928 is 1 mol, 2 g is: 2/58.43976928 = 0,034 moles.
