Benzene be B

Toluene be T

We have made then one lettered to make things easier

$\sf P^0_B=95.1mmHg,P^0_T=28.4mmHg$
$\sf x_B=x_T=0.5$

$\\ \rm\Rrightarrow \dfrac{P^0_B-P_B}{P^0_B}=x_B$

$\\ \rm\Rrightarrow 95.1-P_B=95.(0.5)$

$\\ \rm\Rrightarrow 95.1-P_B=47.55$

$\\ \rm\Rrightarrow P_B=47.55mmHg$

And

$\\ \rm\Rrightarrow \dfrac{P^0_T-P_T}{P^0_T}=x_T$

$\\ \rm\Rrightarrow 28.4-P_T=28.4(0.5)$

$\\ \rm\Rrightarrow P_T=14.2mmHg$

Total vapour pressure

28.4+95.1
123.6mmHg

Answer:

The answer is " $42537.93 \ C$ ".

Explanation:

Molar mass : $Z_n = 65.38 \ \frac{g}{mol}\\\\$

$\to Zn^{2+} + 2e^{-} = Zn\\\\$

$\therefore\\\\ \to 65.38 \ g \ of\ Z_n \ require: \\\\ \to 2 \times 96500\ C\\\\\to 14.41 \ g\ require,\\\\ \to \frac{(14.41 \times 2 \times 96500)}{65.38} \ \frac{g}{mol} = 42537.93 \ C$

Answer:

Yes, precipitation of barium iodate will occur.

Explanation:

Molarity of barium nitrate solution = 0.050 M

Volume of barium nitrate solution =15.0 mL = 0.0150 L

1 mL = 0.001 L

Moles of barium nitrate = n

$n=0.050 M\times 0.0150L=0.00075 mol$

$Ba(NO_3)_2(aq)\rightarrow Ba^{2+}(aq)+2NO_3^{-}(aq)$

Moles of barium ions: $1\times 0.00075 mol=0.00075 mol$

Molarity of potassium iodate solution = 0.10 M

Volume of potassium iodate solution =100.0 mL = 0.1000 L

1 mL = 0.001 L

Moles of potassium iodate = n'

$n'=0.10 M\times 0.1000 L=0.01 mol$

$KIO_3(aq)\rightarrow K^{+}(aq)+IO_3^{-}(aq)$

Moles of iodate ions = $1\times 0.01 mol=0.01 mol$

After mixing of both solution in 250 mL in erlenmeyer flask

Volume of the final solution = 250 mL = 0.250 L

Concentration of barium ions in 250 mL solution :

$[Ba^{2+}]=\frac{0.00075 mol}{0.250 L}=0.003 M$

Concentration of iodate ions:

$[IO_3^{-}]=\frac{0.01 mol}{0.250 L}=0.04 M$

Solubility product of barium iodate, $K_{sp}=4.01\times 10^{-9}$

Ionic product of the barium iodate in solution : $K_i$

$Ba(IO_3)_2\rightleftahrpoons Ba^{2+}+2IO_3^{-}$

$K_i=[Ba^{2+}][IO_2^{-}]^2$

$K_i=0.003 M\times (0.04 M)^2=4.8\times 10^{-6}$

$K_{sp}$ ( precipitation)

As we can see, the ionic product of the barium iodate is greater than the solubility product of the barium iodate precipitation of barium iodiate will occur in 250 mL of final solution.
