How do I solve the following problems? **Determining the Mass of Elements from Chemical Compounds**When analyzing chemical compounds, it is often useful to determine the mass of specific elements within a given amount of the compound. ### Example Problems:1. **How much C is present in 10.0 g of CO₂?** To solve this, we will need to use the molar mass of carbon dioxide (CO₂), which comprises one carbon (C) atom and two oxygen (O) atoms. The mass of CO₂ can be calculated as follows: - Molar mass of CO₂ = (Mass of C) + 2*(Mass of O) - Molar mass of C = 12.01 g/mol - Molar mass of O = 16.00 g/mol Therefore, - Molar mass of CO₂ = 12.01 + 2*(16.00) = 44.01 g/mol We can then find the proportion of carbon in CO₂: - Mass fraction of C in CO₂ = Mass of C / Molar mass of CO₂ - Mass fraction of C in CO₂ = 12.01 g / 44.01 g = 0.273 Multiply this fraction by the given mass of CO₂ to find the mass of C: - Mass of C in 10.0 g of CO₂ = 0.273 * 10.0 g = 2.73 g **Mass of C:** ![Input box for mass of C](inputbox) g2. **How much H is present in 4.10 g of H₂O?** Similarly, we find the molar mass of water (H₂O), which is composed of two hydrogen (H) atoms and one oxygen (O) atom: - Molar mass of H₂O = 2*(Mass of H) + (Mass of O) - Molar mass of H = 1.01 g/mol - Molar mass of O = 16.00 g/mol Therefore, - Molar mass of H₂O = 2*(1.01) + 16.00 = 18.02 g/mol We then find the proportion of hydrogen in H₂O: - Mass fraction of H in H₂O = 2*(Mass of H) / Molar
