Does the compounds C2H2 and C6H6 have the same percent composition by mass?

It does not necessarily mean that. For example glucose (C6H12O6) and formaldehyde (CH2O) have the same percentages of elements by mass, but are two very difference compounds.

How many grams of C6H6 are present in 12.7 moles of C6H6?
Molar mass C6H6 = 12.0x6 + 1.00x6 = 72 + 6 = 78 g/mole12.7 moles x 78 g/mole = 990.6 grams = 991 g (to 3 significant figures)
What is non organic compounds?
An inorganic compound is one that is not derived from a natural or living source. Unlike organic solvents which contain C-H bonds, inorganic compounds generally form ionic bonds between a cation and an anion forming salts. Examples: inorganic: NaOH, SiO2, MgSO4 organic: C6H6, C6H14
How many moles of C6H6 are there in195g of C6H6?
C6H6 is the molecule of benzene and it's molecular weight is 78, calculated as 6 x 12 +6 x 1=78 and you will understand it if you know some basics of chemistry. then, You know that each mole of a molecule weighs exactly those number of grams as much as is its molecular weight. That means if a molecule has 'M' as its molecular weight, then one mole of it weighs exactly M grams when actually weighed using a weighing machine. This means one mole of benzene weighs 78 grams. then 195 grams of C6H6 has (1/78)x195 moles or 195/78 moles in it.
What are examples of carbon arranged in a crystal lattice?
examples of NONPOLAR covalent molecular crystals: hydrogen (H2), oxygen (O2), methane (CH4),Macrophage inflammatory protein-1β (CCl4),Benzene (C6H6)examples of POLAR covalent molecular crystals: Ammonia (NH3), Water (H2O)
What compounds each as a liquid would be expected to be the best solvent for carbon disulfide nh3 ch3oh h2o c6h6 or hbr?
C6H6 would be good, as both CS2 and C6H6 are organic and non polar.
Which of the following compounds does not contain nitrogen?
There are many compounds that don't contain nitrogen: CO2, NaCl, H2O, C6H6, CuCl2...
Why is it important to reduce coefficient in a balanced equation to the lowest possible whole number?
It is not always important. In chemistry, for example, you would never reduce C2H2 (acytelene) and C6H6 (benzene) to CH.
What is the molecular formula of a compound with an empirical formula of CH?
CH could represent the moleculaes H-C///C-H (Ethyne/Acetylene) Or Benzene , which is C6H6
What is an example of percent mass?
you have 40.0 ml of C6H5CH3.....that is put into 75.0 ml of C6H6,what is the percent volume of C6H5CH3?
What is a formula that shows the simplest whole number ratio of atoms in a compound?
It is an over-simplified chemical formula which is just plain wrong. For example, acetylene is C2H2 and benzene is C6H6. Nobody would write these as CH.
What compound burns with a black flame?
The organic compounds having high ratio of carbon burn with black smoke (SOOT) as Aromatic compounds for example Benzene, C6H6.
Is c6h6 a hydrocarbon?
C6H6 is this a hydrocarbon
C6H6 IS A BENZEN?
yes C6H6 IS Benzen.
What compounds is the simple aromatic compound?
The compounds most simple is Benzene because is an organic chemical compound with the molecular formula C6H6.Is a natural constituent of crude oil, and is one of the most basic petrochemicals
What type of formula where the atoms are in the smallest whole number ratio?
It is a poor chemical formula. Poor, because it would not distinguish between acetylene C2H2 and benzene C6H6 for example. It is useful only to the extent that it shows the proportions of the atoms in molecule of the compound.
What is the chemical formula for benzen?
Formula: C6H6
