Where NA = 6.022 x 1023. In above glucose sample, the no. of glucose molecules = 0.01 x 6.022 x 1023 = 6.022 x 1021. Remember that one mole of any substance contains Avogadro number of particles (may be atoms or molecules or ions etc.). If the substance is molecular, the number molecules will be equal to 6.022 x 1023.
