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.
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.
WARNING! Long answer! The molecular formula is "C"_6"H"_5"NO"_2. > I believe the correct vapour density is 61.5. See below. Our first task is to calculate the empirical formula of the compound. The.
A compound has a molecular mass of #"180 u"#, contains six carbon atoms and six oxygen atoms, and an unknown element, #"Z"#. What is the unknown element and what is the chemical formula of the.
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 Formula is: E=mc^2 The formula stated above is Einstein's one of the most famous equation. What this formula represents is that Energy (E) is equal to product of Mass (M) and Speed of light in.
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
The molar mass of the coumpound is 280 g/mol and its molecular formula is C_20H_40. So, you know that when you dissolve 100 mg of your unknown compound in 1 g of benzene, you get a lower.
Let the molecular formula of HC be CxH y And the balanced equation of the combustion reaction of the HC in oxygen is CxH y + (x + y 4)O2(g) → xCO2(g) + y 2H 2O(l) So by this equation the.
To find the molar mass of a nitrogen molecule, we'll first realize its chemical formula, which is "N"_2. Most periodic tables list the molar masses (same number as atomic mass) of all the elements under.
