Find the molecular mass of glucose (C_6H_12O_6) and calculate the mass

1.	Find the molecular mass of glucose (C_6H_12O_6) and calculate the mass of one molecule of it.
Answer» Solution :The MOLECULAR formula of GLUCOSE is `C_(6)H_(12)O_(6)`. The molecular mass of glucose: `=(6 xx 12.01) + (12 xx 1.008) + (6 xx 16.0) = 180.156` amu Hence, the gram molecular mass of glucose will be `180.156` g and will contain `6.022 xx 10^23` molecules. `therefore`The mass of one MOLECULE of glucose `=(180.156)/(6.022 xx 10^(23)) = 2.992 xx 10^(-22) g`
