How would i separate uncooked rice from salt rocks?

Mixing the 3 with water would dissolve the salt. Filtration would then yield salt water and a rice/pepper mix on the filter. Evaporation of the salt water would afford dry salt. THe other two are harder being organics - trial and error might lead you to a solvent that would dissolve pepper, but not rice or vice-versa. Filtration and evaporation could be used again, but I have no idea about which solvent to use.

To use chromatography you would need a solvent for all three or a sequence of solvents to sequentially dissolve each component.

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
