diantara senyawa berikut yang memiliki nilai Mr paling besar adalah... (diketahui ArH=1; ArCl=35,5; ArN=14; ArO=16; ArS=32; ArCa=40) A.HCl B.HNO3 C.H2SO4 D.Ca(O

Ini ya jawabnya.....

A.HCl
Mr= ArH + ArCl
=1+ 35,5
= 36,5
B.HNO3
Mr= ArH + ArN + 3.ArO
= 1 + 14 + 3.16
= 1 + 14 + 48
=63
C.H2SO4
Mr= 2.ArH + ArS + 4.ArO
=2.1 + 32 + 4.16
= 2 + 32 + 64
=98
D.Ca(OH)2
Mr= ArCa + 2ArO + 2ArH
= 40 + 2.16 + 2.1
= 40 + 32 + 2
=74
E.NH4OH
Mr= ArN + 4ArH + ArO + H
= 14 + 4.1 + 16 + 1
= 14 + 4 + 16 + 1
=36

jadi jawabnya
C.H2SO4
