Question

Hich formula can be used to calculate the molar mass of hydrogen peroxide (H2O2)? (5 points)

Answer 1

Answer:

Answers are 34.6 grams and objective d.

Answer 2

Answer:

which formula can be used to calculate the molar mass of hydrogen peroxide (H2O2)?

» d.2 x molar mass of H + 2 x molar mass of O

Explanation:

Since we've two hydrogen atoms and two oxygen atoms, we multiply each mass by 2

$= (2 \times hydrogen) + (2 \times oxygen) \\ = (2 \times 1) + (2 \times 16) \\ = 2 + 32 \\ = 34 \: g$

Which of the following statements best defines the actual yield of a reaction?

» d.The ratio of measured yield over stoichiometric yield
