What is the empirical formula mass? What is empirical formula mass of H₂O₂?
Answers
Answer:
A hydrogen peroxide molecule is made of two hydrogen atoms and two oxygen atoms, so its molecular formula is H2O2.
Explanation:
Empirical Formula - A formula that gives the simplest whole-number ratio of atoms in a compound. Start with the number of grams of each element, given in the problem. the mass of each element = the percent given. Convert the mass of each element to moles using the molar mass from the periodic table.

Answer:
The molecular formula H2O2 is a multiple of the empirical formula. We can know this because the ratio of 2H:2O is not the lowest whole number ratio. By dividing the subscripts by 2 , we can determine the lowest whole number ratio, which is 1H:1O . Therefore, the empirical formula for H2O2 is HO .
