Answer:
The formula for sucrose is
C12H22O11
moles sucrose = mass / molar mass
= 6.0 g / 342.30 g/mol
= 0.017528 mol
the formula shows that each sucrose molecule has 22 H atoms
so moles H = 22 x moles sucrose
= 0.3856 mol
mass H = molar mass x moles
= 1.008 g/mol x 0.3856 mol
= 0.3887 g
= 0.39 g ( 2 sig figs)
