How many molecules are in 6.34 g nacl

1. One teaspoon is equal to 5 grams. So, the number of moles of NaCl can be determined by dividing 5 g by the molecular weight of NaCl which is 58.45 g/mol.

5/58.45 = 0.0855 mol NaCl

2. Since the stiochiometric ratio of Na and Cl in NaCl is 1:1, the number of moles of Na and Cl are the same as that of NaCl.

3. To get the number of atoms, we multiply the number of moles by the Avogadro's number which is 6.022x10^23. Since Na and Cl have the same number of moles, they also have the same number of atoms which is:

0.0855 (6.022x10^23) = 5.15x10^22 atoms

4,5,6. The compound with the greatest amount of teaspoon is the one with the greater density and lower molecular weight. You can convert volume to number of moles of atoms if you know the density and the molecular weight of the substance.
