$Mass \space of \space carbon \space dioxide=88g$
According to law of conservation of mass, the mass of reactants is equal to the mass of the products The balanced chemical equation for the reaction can be written as $C_2H_5OH+3O_2\rightarrow 3H_2O+2CO_2$ $Mass \space of \space reactants=Mass \space of\space ethanol+Mass \space of\space oxygen=46+96=142g$ $Mass\space of\space products=Mass\space of\space water +Mass \space of \space carbon \space dioxide=54+ Mass \space of \space carbon \space dioxide$ Now $142g=54+Mass \space of \space carbon \space dioxide$ $Mass \space of \space carbon \space dioxide=88g$
