Question

What mass of PbCl2 can form from 0.235L of 0.110 M KCl solution if there is plenty of Pb(NO3)2 present? Molar mass of PbCl2 is 278.1g/mol

Balanced reaction:

2KCl(aq) + Pb(NO3)2(aq) -> PbCl2(s) + 2KNO3(aq)

Answer 1

Answer #1

Moles = molarity & volume (2) Molarity of KCN = 0.110m Volume of KCN = 0.235 L .. moles of KCN = 0.110 x 0.235 = 0.02585 mol
