Jawaban:

Kelarutan Ag Br dalam air:

Ag Br space rightwards harpoon over leftwards harpoon space Ag to the power of plus sign and Br to the power of minus sign s space M space space space space space space space space s space M space space space space s space M 

K subscript sp space Ag Br double bond open square brackets Ag to the power of plus sign close square brackets open square brackets Br to the power of minus sign close square brackets 5 cross times 10 to the power of negative sign 13 end exponent equals s point s space space space space space space space space space space space space s equals square root of 5 cross times 10 to the power of negative sign 13 end exponent end root space space space space space space space space space space space space space space equals 7 comma 07 cross times 10 to the power of negative sign 7 end exponent space M

Kelarutan dalam 100 mL air = 

7 comma 07 cross times 10 to the power of negative sign 6 end exponent space M 

Jadi, kelarutan Ag Br dalalm 100 mL air adalah 7 comma 07 cross times 10 to the power of negative sign 6 end exponent space M.
