V(H2) = 2.24L
m(ppaAgNO3) = 50 g
W(AgNO3) =3.4 %
------------------------
m(AgCL) -?
H2+CL2-->2HCL
V(H2) = 2V(HCL)
V(HCL) = 4.48 L
n(HCL) = V(HCL) / Vm =4.48 / 22.4 = 0.2 mol
m(AgNO3) = 50*3.4% / 100% = 1.7 g
HCL+AgNO3-->AgCL+HNO3
M(AgNO3) = 170 g/mol
n(AgNO3) = m/M = 1.7 / 170 = 0.01 mol
n(AgNO3) = n(AgCL) = 0.01 mol
n(HCL) > n(AgCL)
M(AgCL) = 143.5 g/mol
m(AgCL) = n*M = 0.01*143.5 = 1.435 g
