Question

46.6 grams of mercury II sulfate (HgSO4) reacts with an excess of sodium Chloride (NaCl). How many grams of mercury II chloride (HgCl2) is produced? the other product is sodium sulfate, Na2SO4

Answer 1

`m_(HgCl_2)=42.7gHgCl_2`

Step-by-step explanation:

Hello,

In this case, the undergoing chemical reaction is:

`HgSO_4+2NaCl\rightarrow HgCl_2+Na_2SO_4`

In such a way, the mercury II sulfate (molar mass 296.65g/mol) is in a 1:1 molar ratio with the mercury II chloride (molar mass 271.52g/mol), for that reason the stoichiometry to find mass in grams of mercury II chloride turns out:

`m_(HgCl_2)=46.6gHgSO_4*(1molHgSO_4)/(296.65 gHgSO_4)*(1molHgCl_2)/(1molHgSO_4) *(271.52gHgCl_2)/(1molHgCl_2) \\\\m_(HgCl_2)=42.7gHgCl_2`

Best regards.
