Question

calulate molar mass of sulphuric acud give the electronic configuration of 1) Al atom its ion 2)O atom and its ion​

Answer 1

Answer:

thank you for your answer

Answer 2

Answer:

molar mass of H2SO4 is 98

H=1 S=32 O =16

2×1+32+16×4

=98

1) electronic configuration of Al(13) 1s2 2s2 2p6 3s2 3p1

Al ion Al+3 1s2 2s2 2p6

mass of Al is 27

2) electronic configuration of O(8) is 1s2 2s2 2p4

O-2 ion 1s2 2s2 2p2

mass of O is 16
