Explanation / Answer

PART A

Balanced equation:
2 AgNO3 + CaCl2 = 2 AgCl + Ca(NO3)2

Mass of silver nitrate (Molar mass169.87 g/mol) to prepare 1.32 L of 0.151 M = 1.32 x 0.151 x 169.87 = 33.86 gm AgNO3 is needed

PART B

Moles of AgNO3 = 1.32 x 0.151 = 0.19932 Moles

Moles of CaCl2 needs = 0.19932 /2 = 0.09966 Moles

Concentration of CaCl2 = 0.09966 x 1000 / 3350 = 0.0297 M
