Ответ:
дано
m( ppa C6H5NH2) = 102 g
W(C6H5NH2) = 2%
------------------------
m(HCL)-?
m(C6H5NH2) = 102 * 2% / 100% = 2.04 g
C6H5NH2+HCL-->C6H5CL+NH3
M(C6H5NH2) = 93 g/mol
n(C6H5NH2) = m/M = 2.04 / 93 = 0.02 mol
n(C6H5NH2) = n(HCL)
M(HCL) = 36,5 g/mol
m(HCL) = n*M = 0.02 * 36.5 = 0.73 g
ответ 0.73 г
