How many carbon atoms are in 77.28g of ethane?
To find the number of carbon atoms in 77.28g of ethane (C₂H₆), first calculate the number of moles of ethane by dividing the mass by its molar mass (30.07 g/mol). Then, since each molecule of ethane contains 2 carbon atoms, multiply the number of moles by Avogadro's number (6.022 x 10²³) to find the number of carbon atoms.
How many molecules of ethane gas C2H6 are in 15 grams of the compound?
To calculate the number of molecules in 15 grams of ethane (C2H6), first find the molar mass of C2H6, which is 30.07 g/mol. Next, calculate the number of moles in 15 grams using the formula: moles = mass / molar mass. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many grams of carbon are in 1.00 mol of carbon?
moles = mass/relative atomic mass 1 = mass/12 mass = 12 x 1 = 12 grams
How many grams of oxygen gas will react with 77.28 grams of ethane in 2 C2H6 plus 7 O2 equals 4 CO2 plus 6H2O?
First, find out how many moles of C2H6 that you have: Carbon is 12 grams per mole, and H is 1 gram per mole, so C2H6 is (2*12 + 6*1)grams = 30 grams per mole. So you have (77.28/30 = 2.58) moles. Every 2 moles of C2H6 reacts wilth 7 moles of O2 so it will react with 7/2*2.58 moles = 9.02 moles of O2.O2 is 32 grams per mole, so (9.02 moles)*(32 grams/mole) = 288.64 grams.
What is the mass of carbon in carbon dioxide?
The mass of carbon in carbon dioxide is 12 grams per mole.
How many carbon atoms are in 77.28g of ethane?
To find the number of carbon atoms in 77.28g of ethane (C₂H₆), first calculate the number of moles of ethane by dividing the mass by its molar mass (30.07 g/mol).

How many moles of C are in 32.6 g of C2H6?
To find the number of moles of carbon (C) in 32.6 g of ethane (C2H6), first calculate the molar mass of C2H6, which is approximately 30.07 g/mol. Since each molecule of C2H6 contains 2 moles of carbon, the total number of moles of C in 32.6 g of C2H6 can be found by dividing the mass by the molar mass and then multiplying by 2. This gives: [ \text{Moles of C} = \left(\frac{32.6 , \text{g}}{30.07 , \text{g/mol}}\right) \times 2 \approx 2.16 , \text{moles of C}. ]

One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.
How many moles of carbon are there in 500 mole of c2h6?
The subscript in the chemical formula C2H6 tells you that one C2H6 molecule contains 2 carbon atoms. Or, in terms of moles, 1 mol C2H6 contains 2 mol C. This mole ratio can be used as a conversion factor. 500 mol C2H6 x 2 mol C = 1000 mol C ........................1 mol C2H6
What is the mass in grams of 4.5 moles of carbon?
The mass of 4,5 moles of carbon is 54,04815 g.
What is the mass of 1 mole of carbon atom?
We use the equation: Mass = Number of moles * Molecular or atomic mass Since the number of moles is 1 ("one mole of carbon-12 atoms") and the atomic mass of carbon-12 atoms is 12, hence the mass would be 12 grams. Note that the unit grams (g) is used here, as it is the SI unit for mass measurement. I hope this is useful! :)
How much does one mole of carbon atom weight?
1/(6.02214 x 1023) = 1.66054*10-24 molesC-atoms= 1 C-atom
