                During photosynthesis a six carbon atom molecule glucose  is formed. Calculate its molecular mass. (Atomic mass C= 12.0 u, H = 1.0 u, 0 = 16.0 u) 

    Answer:

      Molecular mass of glucose = 6 x at. mass of C + 12 x at. mass of H + 6 x at. mass of O = 6 x 12 + 12 x 1 + 6 x 16 =72 + 12 + 96
