"m"("AgNO"_3) = 581.4 "g"

Explanation:

The formula for moles of a (solid) compound is:

"n" = "m"/"Mr" where "n" is the number of moles, "m" is the mass of the substance in grams and "Mr" is the molar mass of the substance.

We can rearrange this formula given the no of moles and the molar mass:

"m" = "nMr"

"Mr"("AgNO"_3) =170 "g" "mol"^-1

"m"("AgNO"_3) = 3.42 xx170 = 581.4 "g"
