The answer is 2,17 moles carbon.
The reaction is:2 C + O2 = 2 COSo 2,1 moles are obtained.
1,4 moles carbon monoxide are produced.
This is a chemical calculation. 2.5 moles will C reacting with O2.
The atomic mass of carbon, C is 12.0Amount of C = mass of sample/molar mass = 0.170/12.0 = 0.0142mol There are 0.0142 moles of carbon in a 0.170g pure sample.
The answer is 2,17 moles carbon.
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
350 g C2H6 x 1 mole C2H6/30 g x 2 moles C/mole C2H6 x 12 g/mole C = 280 g carbonDone another way: %C = 24/30 (x100%) = 80% 0.8 x 350 g = 280 grams carbon
The molar mass of an element is its atomic weight in grams. The atomic weight is on the periodic table. 1 mole C = 12.0107 g C. To calculate the number of moles in 80 g of C, do the following: 80 g C x (1 mole C/12.0107 g C) = 6.66 mole C = 7 mole C* *This answer has been rounded to the proper number of significant figures. When multiplying or dividing, the answer is rounded to the fewest significant figures used in the calculation. 80 only has one significant figure. Refer to the related link below concerning significant figures.
A hydrocarbon is C2H6.
77.28 grams C2H6 (1 mole C2H6/30.068 grams)(2 mole C/1 mole C2H6)(6.022 X 10^23/1 mole C) = 3.096 X 10^24 atoms of carbon
C2h6
How many moles of C are needed to react with 0.490 mole SO2?
The same. 0.233 moles C (1mol C/1mo CO2 ) = 0.233 moles of Carbon.
'c' C2H6 ( Ethane) The others are INORGANIC Molecules. Remember , organic chemicstry deals with the chemistry or CARBON compounds. If no carbon is present then it is INORGANIC.
1,4 moles of CO are produced.
Use stoichiometry to convert grams of Carbon to moles of carbon and solve. 28093g C *(1mol C/12.011g C)= 2338.94mol C
