How many moles of carbon dioxide are there in 19 grams of carbon dioxide?
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
If hexane was burned in a limited supply of oxygen the combustion would not be complete?
This depends on how much hexane was being burned and how much oxygen was present.Because the complete combustion of carbon involves placing two moles of oxygen on one mole of carbon plus the formation of water, you would need 19 moles of diatomic oxygen for every one mole of hexane.1 C6H14 + 19 O2 --> 6 CO2 + 7 H2O
How many moles are in 19 g of NO2?
0.41
How many times more carbon is in the oceans than in the atmosphere?
The oceans contain about 50 times more carbon dioxide (CO2) than the atmosphere and 19 times more than the land biosphere.
How many moles of oxygen are required for the complete combustion of heptane?
The balanced equation for complete combustion of heptane is C7H16 + 11O2 ---(ignition)---> 7CO2 + 8H2O. For each moelcule of heptane, you would need 11 molecules of oxygen gas.
How many moles of nitrogen are there in 29 grams of nitrogen?
There are 29/14, or just over 2 moles of nitrogen in 19 grams.
Hexane and oxygen gas as a reaction?
The outcome of the reaction is carbon dioxide and water
How many moles are in 3 moles of HF?
Moles = Mass/Molar Mass.Using this equation, we can take 25/(1.0 + 19) and find that it is equal to 1.25 moles.Keep in mind that very few significant figures were used for this example (2), and that if accuracy is to be expected, as many as possible should be used.
If you have 85.5 grams of fluorine which has a molar mass approxidmatley 19 g mol how many moles of fluorine do you have?
4.5
How many moles of O2 are needed to burn 1.50 moles of C8H18?
Balance this combustion reaction first! 2C4H10 + 13O2 -> 8CO2 + 10H2O 0.86 moles C4H10 (13 moles O2/2 moles C4H10) = 5.6 moles of oxygen required ----------------------------------------
What number of moles does 32.00 g of LiF represent?
I mole of LiF is (7 + 19) = 26 g. Thus 32 g is 32/26 moles = 1.23 moles.
How many atoms of carbon in glucose in 3.31x10 to the power of 19 molecules of glucose?
19.86 x 1019 carbon atoms (just times it by 6, the number of carbon atoms in one glucose molecule)
