Writing of the subshells
Explanation:
Given configuration:-
![\\ \sf\longmapsto 1s^22s^22p^63s^23p^63d^{10}4s^2](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%201s%5E22s%5E22p%5E63s%5E23p%5E63d%5E%7B10%7D4s%5E2)
Actual configuration:-
![\\ \sf\longmapsto 1s^22s^22p^63s^23p^64s^23d^{10}](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%201s%5E22s%5E22p%5E63s%5E23p%5E64s%5E23d%5E%7B10%7D)

Explanation:
mass = no. of moles x molar mass (Mr)
i- mass = 10.2 mol x 30 g/mol
= 306 g
ii- mass of potassium hydroxide = 0.0146 mol x 56g/mol
= 0.8176g
mass of calcium hydroxide= 0.0146mol x 74 g/mol
= 1.0804g
