Glucose #=># #C_6H_12O_6#

Number of hydrogen atoms # = 7.22656908 xx 10^24#

First, calculate the number of moles.

#"Moles"# = #"grams/molecular mass"#

#=(180 g)/180_(g/(mol)# # -># grams cancel out

#=# 1 mol

There are 12 hydrogen atoms in glucose, and to find the number of atoms you need to use Avogandro's Number #(6.0221409 xx 10^23)#

Total no. of hydrogen atoms = #("no. of hydrogen atoms") * ("no. of moles") * (6.0221409 xx 10^23)#

# = (12) * (1) * (6.0221409 xx 10^23)#

# = 7.22656908 xx 10^24#
