This is part of a continuing problem from the previous carbohydrate sample. Use that data to continue the calculation. A 12.915 g carbohydrate sample of composed CHO was analyzed by combustion analysis from which was obtained 18.942 g CO2 and 7,74 g H2O. How many grams of O are in the sample? Input the value of O here. Hint: Consider the difference between the original sample mass and the sum of the C and H mass. Table molar mass (g/mol): C 12.00, O 16.00, H 1.008.

Question
Transcribed Image Text:This is part of a continuing problem from the previous carbohydrate sample. Use that
data to continue the calculation.
A 12.915 g carbohydrate sample of composed CHO was analyzed by combustion
analysis from which was obtained 18.942 g CO2 and 7,74 g H2O. How many grams of
O are in the sample? Input the value of O here.
Hint: Consider the difference between the original sample mass and the sum of the C and H
mass.
Table molar mass (g/mol): C 12.00, O 16.00, H 1.008.
Expert Solution
Step 1
Given,
Mass of carbohydrate sample = 12.915 g
Carbohydrate sample composed of CHO
On combustion:
Mass of CO2 obtained = 18.942 g
Mass of H2O obtained = 7.74 g
Molar mass of C = 12.00 g/mol
Molar mass of O = 16.00 g/mol
Molar mass of H = 1.008 g/mol
Mass (in grams) of O in the sample = ?
