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.

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 has a mass of …

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 "CuS"_2. > An empirical formula is the simplest whole number molar ratio of the elements in a compound. Your compound contains "0.768 mol Cu" and "1.56 mol S".

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 formula"=nxx"empirical …

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

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

The density formula can be used to determine the mass of the #"SO"_2# in the flask.

Aug 31, 2015 · Since at the top of its trajectory its velocity is equal to zero, you can use the same formula to determine the distance #h_"down"# it travelled until its velocity reached 17 m/s.

This is all about the charge on the anions. Step 1: determine the identity of the anion(s). Generally these will end in -ide, -ite, -ate. Step 2: Determine the charge on the anions. If the anion contains F, Cl, Br, …
