Surfing For Agcl Is A Solid?

Jenny asks…Can someone explain to me how to do this chemistry problem?What mass of KCL is needed to react with 13.4 mL of a 2.34 molar solution of AgNO3 to produce solid AgCl and KNO3Nancy answers:Given: 13.4 mL 2.34M AgNO3; AgCl and KNO3
Find: Mass fof KCL

Plan: mL -----> L -------> M AgCl -------> g KCL

13.4 mL = .0134 L
Molar Mass KCL = 39.10 + 35.45 = 74.55g

Write the balance formula

AgNO3(aq) + KCL(aq) -----------> AgCl(s) + KNO3

Solution:

.0134 L AgNO3 x (2.43 M AgNO3
