(Methyl cyanide, also known as acetonitrile, upon hydrolysis yields acetic acid.)

Explanation

The decomposition reaction is: 

ZnCO 3(s)→ZnO(s)+CO 2(g) One mole of ZnCO₃ produces one mole of CO₂, so 10 moles will produce 10 moles of CO₂.

The molar mass of CO₂ is: 

CO₂=12+(16×2)=44g/mol Therefore, 

10 moles of CO₂=10×44=440g.
