Nov 1, 2017 · There is an old joke on the dangers of dihydrogen monoxide. But of course "dihydrogen monoxide" is simply water, i.e. H_2O...and a chemist would never call it anything …

Apr 23, 2018 · Your unknown gas is ethane and its molecular formula is C_2H_6. So, you know that you're dealing with a hydrocarbon, which is a compound that contains only carbon and …

Given that 1.41xx10^22 molecules of Styrene weigh 2.44g.We can write 1 mol or 6.03xx29^23 molecules of Styrene will weigh (2.44xx6.023xx10^23)/ (1.41xx10^22)g~~104g "Hence molar …

Calculate the index of hydrogen deficiency (IHD) An alkane with five "C" atoms has the molecular formula "C"_5"H"_12. Compound A has only eight "H" atoms. ∴ "IHD" = (12-8)/2 = 4/2 = 2 …

Hence, 6C* (12g)/C + 14H* (1g)/H approx 86g Which is characteristic of an alkane with the molecular formula C_6H_14, Moreover, its empirical formula (the lowest ratio of atoms) is …

The molecular formula is C_4H_10 n= V/24 = 9.6/24 = 0.4mol Mr = M/n = 23.2/0.4 = 58 gmol^-1 Since the formula mass of C_2H_5 is 29, it follows that the molecule contains 58/29, or 2 …

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 …

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 …

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 …
