What is the quantity of water produced when $34.2 \ g$ of cane sugar is treated with concentrated $H_2SO_4$ under normal conditions of temperature and pressure (in $g$)?

$A$ pre-weighed vessel was filled with oxygen at $N.T.P.$ and weighed. It was then evacuated,filled with $SO_2$ at the same temperature and pressure,and again weighed. The weight of oxygen will be
