Answer:


m_(HClO_3)=12.7gHClO_3

Step-by-step explanation:

Hello,

Considering the reaction:


3Cl_2(g)+3H_2O(l)-->5HCl+HClO_3

The molar masses of chlorine and chloric acid are:


M_(Cl_2)=35.45*2=70.9g/mol\\M_(HClO_3)=1+35.45+16*3=84.45g/mol

Now, we develop the stoichiometric relationship to find the mass of chloric acid, considering the molar ratio 3:1 between chlorine and chloric acid, as follows:


m_(HClO_3)=31.6gCl_2*(1molCl_2)/(70.9gCl_2) *(1molHClO_3)/(3mol Cl_2) *(85.45g HClO_3)/(1mol HClO_3) \\m_(HClO_3)=12.7gHClO_3

Best regards.
