Question

what is the mass of one sodium atom in gram​

Answer 1

Answer:

This means that a single atom of sodium weighs 23 atomic mass units (AMUs), but it also means that one mole of sodium atoms weighs 23 grams. Hence 6.02 x 10^23 atoms of sodium weight a total of 23 grams. This means that if we divide 23 grams by the number of atoms, we should have the weight of a single atom.

as the gram atomic weight of sodium is 23, so 23 g of Na will contain 1 mole of Na atoms. Therefore, 11.5 g will contain 0.5 mole of Na atoms which is equal to 3.011*10^23 atoms of Na

22.99 g

To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms. For example, the molar mass of NaCl can be calculated for finding the atomic mass of sodium (22.99 g/mol) and the atomic mass of chlorine (35.45 g/mol) and combining them.
