a. \(C_6H_5NH_2 + 3Br_2 \rightarrow C_6H_2Br_3NH_2\downarrow + 3HBr\)
3 mol 330 g
x mol 4,4 g
\(\Rightarrow\) x = 0,04
\(V_{ddBr_{2}3\%} = \dfrac{0,04 \times 160 \times 100}{3 \times1,3} = 164,1 (ml)\)
b. \(C_6H_5NH_2 + 3Br_2 \rightarrow C_6H_2Br_3NH_2\downarrow + 3HBr\)
1 mol 330 g
y mol 6,6 g
\(\Rightarrow\) y = 0,02
\(m_{C_6H_5NH_2} = 0,02 \times 93 = 1,86 (g)\)
