moles of AgNO3 = > 50 * 16.9/(100 * 170) = > 0.05 (approx.)
moles of NaCl = > 5.8 * 5.8/(100 * 58.5) => 0.05
The reaction goes like this:
AgNO3    +    NaCl       --------->            AgCl             +           NaNO3
0.05               0.05                                0                                 0
 0                         0                             0.05
 
mass of agcl = 0.05 * 143.5 => 7.16 g.
Hence this would be the final mass of the precipitate.
