Chlorine can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid, HCl(aq) , as described b

Katyanochek1 [597]

Answer:

$m_{MnO_2}=1.378gMnO_2$

Explanation:

Hello,

In this case, we first apply the ideal gas equation to compute the moles of produced chlorine:

$n_{Cl_2}=\frac{PV}{RT}=\frac{765 Torr*\frac{1atm}{760Torr}*0.385L}{0.082\frac{atm*L}{mol*K}*298.15K} =0.01585molCl_2$

Then, by considering the given reaction, applying the stoichiometry, that shows a 1 to 1 relationship between chlorine and manganese dioxide, we find:

$m_{MnO_2}=0.01585molCl_2*\frac{1molMnO_2}{1molCl_2} *\frac{86.937gMnO_2}{1molMnO_2} \\m_{MnO_2}=1.378gMnO_2$

Best regards.
