What mass of sodium chloride contains 4.59 exp24 formula units?

Answer 1

The gram formula unit mass of sodium chloride is 58.443, and every gram formula unit mass contains Avogadro's Number, 6.022 X 1023 formula units. Therefore, the mass sought is 58.443 X (4.59 X 1024)/(6.022 X 1023) or 445 grams, to the justified number of significant digits.

Answer 2

To find the mass of sodium chloride containing 4.59 x 10^24 formula units, you can first calculate the molar mass of NaCl (58.44 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert formula units to moles. Finally, multiply the number of moles by the molar mass to find the mass of sodium chloride.
