The differnece in the mass of 100 moles of each sodium atoms and sodium ions is 5.48002 g. Compute the mass of an electron.

To compute the mass of an electron, we need to use the given information about the difference in mass between sodium atoms and sodium ions.

1. Find the molar mass of sodium atoms: The given information mentions the difference in mass for 100 moles of sodium atoms and sodium ions. Since we know the molar mass of an atom of sodium is about 23 g/mol, we can calculate the mass of 100 moles of sodium atoms using the formula:

Mass of 100 moles of sodium atoms = 100 moles * molar mass of sodium atoms

2. Find the molar mass of sodium ions: The difference in mass between sodium atoms and sodium ions is given as 5.48002 g. So, we can express the mass of 100 moles of sodium ions using the formula:

Mass of 100 moles of sodium ions = (Mass of 100 moles of sodium atoms) + 5.48002 g

3. Calculate the difference in mass between 100 moles of sodium ions and sodium atoms: To determine the mass of a single sodium ion, we need to find the difference in mass between one sodium ion and one sodium atom. We can divide the mass difference given in the question by Avogadro's number (6.022 x 10^23) to obtain the mass difference per ion.

Mass difference per ion = (Mass of 100 moles of sodium ions - Mass of 100 moles of sodium atoms) / Avogadro's number

4. Calculate the mass of an electron: Since the sodium ion is formed by losing an electron, the mass difference per ion should represent the mass of a single electron. Hence, the mass of an electron can be calculated by taking the calculated mass difference per ion.

Mass of an electron = Mass difference per ion

Once you have the calculated mass of an electron, you can compare it to the known value of approximately 9.10938356 x 10^-31 kg to verify your answer.
