Well, we need a stoichiometric equation...and we assumes complete combustion of the sugar...I make it approx. #40*g#...

Explanation:

#underbrace(C_6H_12O_6(s) + 6O_2(g))_(6xxC+12xxH+18xxO) rarr underbrace(6CO_2(g) + 6H_2O(l)+Delta)_(6xxC+12xxH+18xxO)#

And so we interrogate the molar quantity of glucose..

#-=(35*g)/(180.16*g*mol^-1)=0.194*mol#

And so we need SIX EQUIV dioxygen...

#0.194*molxx6xx32.00*g*mol^-1=??*g#
