Answer:

0.202M

Explanation:

Balanced equation is:

Fe + 2AgNO3 = Fe(NO3)2 + 2Ag
#darr# ........#darr#
56g .....2(108)g

so,
#darr#....... #darr#
0.2g ...... 1.2g

means 0.2g iron reacts with 1.2g of AgNO3 completely to displace all silver.
now,
Molarity, M=(number of moles of solute)/(volume of solution in litres)
#rArrM={(1.2)/(170)}/{35*10^(-3)} =0.202M#
