You should calculate it by using the percentage by mass of the hydrogen atoms. 3.5mole of glucose is 3.5(12*6+1*6+16*6)g =609g ==>ans:[(1*6)/(12*6+1*6+16*6)]*609=21g ans is c.

you should know the formular to calculate all the question of the chapter of 'Reacting masses'. eg. mass / molar mass=no of mole no of mole*avagadros=no of particles ...and so on..

50000(1+5/100)[1+(3/12)/100]^(2*12)
