Question

How do I solve this  ? 

6. Calculate the theoretical number of moles of 0, there would be if the hydrogen peroxide were 100%, and not
an aqueous solution.
mol H;O2
1 mol 02
Theoretical moles of 0, = H,0, volume * H,O, density
g H;O2
2 mol H2O2
To use the above equation, calculate the following:
H2O2 volume is the volume (mL) of hydrogen peroxide used: Volume =
ml H2O2
H,0, density is known:
Density = 1.02 g/mL
mol H202
is the reciprocal of the molar mass of H;O2. First write the molar mass of H;02 then
g H202
find the reciprocal.
Molar mass of H202 =
g H2O2/1 mol H2O2
Molar mass of H2 O2 reciprocal
Now you have all of the information needed to solve the equation for the theoretical moles of O2. All you need
to do is fill in the blanks and do the calculations.
