How many moles are in 17.0 grams of h2o2? 0.284 mol h2o2 0.385 mol h2o2 0.500 mol h2o2 0.730 mol h2o2

Option (c) is the correct answer.

Explanation:

Number of moles is defined as given mass of substance divided by molar mass.

Mathematically,    No. of moles =

Molar mass of is 34.015 g/mol.

Therefore, calculate number of moles of as follows.

       No. of moles =

                             =

                             = 0.4997 mol

or,                          = 0.500 mol (approx)

Thus, we can conclude that 0.500 mol is present in 17.0 grams of .

explanation:

if u put 3.74 that means there is three of something if u put .374 that means there is less than 1 of somethin if at makes sense.
