How many moles of carbon are there from the original sample of 11.0 grams of carbon dioxide and 4.50 grams of water with a combustion of 7.50 grams?

Look up the molecular weight of carbon dioxide in the periodic table. The formula for carbon dioxide is CO2, which means one atom of carbon and two atoms or oxygen per molecule of carbon dioxide. Carbon has molecular weight of 12. Oxygen molecular weight is 16. Total 12+16+16= 44
11 grams/44 grams/mole=0.25 moles of carbon
The grams of water and combustion of 7.5 grams are totally irrelevant. They are only given to possibly confuse you.

What is the concentration of carbon dioxide in this sample?
well when the heart pumps then its the sample
Does silicon dioxide contain carbon?
Silicon dioxide contains only silicon and oxygen - no carbon., The only carbon in a sample labelled " silicon dioxide", would be an impurity or contaminant probably on the surface
How would you test a sample of gas to see if it contained carbon dioxide?
take the gas atach it to the flask with limewater....if carbon dioxide is present then it will turn cloudy...thats the answer for test of carbon dioxide i think the answer your looking for is bromthymol blue
Why silicon dioxide cannot be the only compound in the sample of sand?
sand is a mixture, not a compound.. silicon dioxide is just a compound
How many milliliters of nitrogen and oxygen in one sample of dry air?
Dry air is made up (by volume) of Nitrogen (N2) 78.084%, Oxygen (O2) 20.946%, Argon (Ar) 0.9340%, Carbon Dioxide (CO2) 0.03697%, and trace bits of a few other gases. Since these are percent volume numbers the simple multiplication of each by 10 gives the millilitre or cm3 value directly: Nitrogen (N2) 780.84 ml, Oxygen (O2) 209.46ml, Argon (Ar) 9.340ml, Carbon Dioxide (CO2) 0.3697ml
Would a sample of the compound carbon dioxide in your school and another sample of carbon dioxide in Australia have the same composition and properties?
Yes they wouldn't have the same composition but not properties!

Which air sample contains the most carbon dioxide?
the leg

How could you eliminate the carbon dioxide that may be dissolved in a sample of water?
by singing rap

What is left when carbon burns?
if it is a pure sample of C, nothing is left, burning forms carbon dioxide gas which mixes with the air and is gone.
Why carbon di oxide should be remove from water immediately?
Since excess carbon dioxide, if present in water, easily escapes to the atmosphere, tests for carbon dioxide should be performed immediately after collection of water sample (especially for ground water samples which usually contain high carbon dioxide).
What is the mass of CO2?
how much of co2 is released in by fossil fuels
How do you determine Carbon Monoxide Carbon Dioxide Oxygen and Hydrogen contents in a sample of producer gas by Orsat Apparatus?
Type your answer here... we can make the solution of copper chloride for orsat apparatus.
How many moles are in 44g of carbon dioxide?
Multiply the value of 1 mole by 5. 44 g/mol x 5 mol Mole units cancel out, leaving 220g of CO2
How many grams of carbon dioxide are present in a sample containing 80.0 moles of CO2?
80,0 moles of CO2is equal to 3 520,8 g.
