m (Au) + m (Cl 2 ) = m (AuCl 3 ) m (Cl 2 ) = 0.303 – 0.197 = 0.106 g

Throwing some scrap iron in a gold nitrate solution causes the gold metal to precipitate. How many liters of 0.5 M gold nitrate solution would react with 2.8x10<sup>23</sup> particles of iron metal?

Reaction:Au3+ + Fe = Fe3+ + AuV(Au(NO3)3 solution) = 2.8x1023/(6.02x1023)/0.5 = 0.93 LAnswer: 0.93 L
