Answer:
0.625 moles of CO2
Step-by-step explanation:
Remark
The equation used (I take it) is a hydrocarbon burning. If it is not, leave a note on the question. The method I will use is
- Find the moles CH4
- Use the equation to adjust the number of moles of the product. It the balance numbers are the same, move on.
Equation
CH4 + 2O2 ====> CO2 + 2H2O
Givens
10 grams CH4
Solution
Number of moles of CH4
mol CH4 = given mass / molar mass.
given mass = 10 grams
molar mass CH4
- C = 12
- H = 4 * 1 4
- molar mass 16
Moles of CH4
mol = given mass / molar mass
mol = 10 grams / 16 grams
mol = 0.625
Answer
Since the number of moles of CO2 and CH4 are the same in the balanced equation. the answer is 0.625 mols of both.
