Question

41.Compute the difference in masses of one mole each of aluminium atoms and one mole of its ions. (Mass of an electron is 9.1 x 10-28 g). Which one is heavier? In of aluminium atom​

Answer 1

→1 mole of Al atoms is heavier than 1 mole of Al3+ ions. It is because 1 mole of Al atom have e– = 13 x 6.022 x 1023 electrons and 1 mole of Al ion have e“ = 10 x 6.022 x 1023 electrons.

Answer 2

Answer:

꧁P꧁R꧁I꧁N꧁C꧁E꧂

Step-by-step explanation:

➡️ 1 mole of Al atoms is heavier than 1 mole of Al3+ ions. It is because 1 mole of Al atom have e– = 13 x 6.022 x 1023 electrons and 1 mole of Al ion have e“ = 10 x 6.022 x 1023 electrons ...
