The number of moles of oxygen in the compound is B) 3.3 (to two significant figures). This is not the same as the mole ratio. I also showed how to get the mole ratios and empirical formula.

The simplest (or "empirical") formula is C_3H_8O_3 First, we take the masses of the two products and convert these to moles: moles CO_2 = 1.448g-:44.0 g/"mol" = 0.0329 mol Since CO_2 …

Jan 24, 2018 · Well, since it has an empirical formula of C3H 4O3, then we can find its "empirical" mass. Carbon has a mass of 12 atomic units. Hydrogen has a mass of 1 atomic unit. Oxygen …

Styrene is also known as ethenylbenzene, vinylbenzene, and phenylethene. It is an organic compound and its chemical formula is #"C"_6"H"_5"CH=CH"_2# Answer link

Explanation: As with all these types of problems it is useful to assume #100*g# of compound, and address the empirical formula on this basis.

The empirical formula is the simplest whole-number ratio of atoms in a compound.

Unknown on these data.... We got an empirical formula of CH... We further know that the molecular formula is a whole number multiple of the empirical formula...i.e. "molecular …

What is the empirical formula of the compound if magnesium is 60.9 and oxygen is 39.1?
