Answer: 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 = \frac{mass of given substance}{molar mass}

Molar mass of H_{2}O_{2} is 34.015 g/mol.

Therefore, calculate number of moles of H_{2}O_{2} as follows.

       No. of moles = \frac{mass of given substance}{molar mass}

                             = \frac{17.0 g}{34.015 g/mol}

                             = 0.4997 mol

or,                          = 0.500 mol (approx)

Thus, we can conclude that 0.500 mol is present in 17.0 grams of H_{2}O_{2}.
