Questions & Answers

Q: How can we calculate the percentage of hydrogen in an organic compound?

To calculate the percentage of hydrogen, we can use the weight of water produced during the combustion reaction. By knowing that 18g of water contains 2g of hydrogen, we can determine the amount of hydrogen in a given sample and calculate the percentage.

Q: How do we calculate the percentage of carbon in an organic compound?

The percentage of carbon can be calculated by using the weight of carbon dioxide produced during the combustion reaction. By knowing that 44g of carbon dioxide contains 12g of carbon, we can determine the amount of carbon in a given sample and calculate the percentage.

Q: What is the formula for calculating the percentage of hydrogen and carbon?

The formula for calculating the percentage of hydrogen is (2 * weight of water) / total weight of organic compound * 100. The formula for calculating the percentage of carbon is (12 * weight of carbon dioxide) / total weight of organic compound * 100.

Q: Can we input the given data directly into a formula to calculate the percentages?

Yes, by using the formulas mentioned earlier and inputting the given data of water, carbon dioxide, and the weight of the organic compound, we can directly calculate the percentages of hydrogen and carbon.
