An organic compound on analysis yielded 2.04g carbon 0.34g hydrogen and 2.73g oxygen calculate its molecular formula if the relative molecular mass of the compound is 60 c = 12 h = 1 o = 16
To determine the molecular formula, we need to find the number of each element in the molecule.
1. Calculate the number of moles for each element:
- Carbon: 2.04 g / 12 g/mol = 0.17 mol
- Hydrogen: 0.34 g / 1 g/mol = 0.34 mol
- Oxygen: 2.73 g / 16 g/mol = 0.17 mol
2. Divide the number of moles of each element by the smallest number of moles (in this case, carbon):
- Carbon: 0.17 mol / 0.17 mol = 1 mol
- Hydrogen: 0.34 mol / 0.17 mol = 2 mol
- Oxygen: 0.17 mol / 0.17 mol = 1 mol
3. The molecular formula is determined by the whole-number ratio of atoms. In this case, the ratios are:
- Carbon: 1
- Hydrogen: 2
- Oxygen: 1
Therefore, the molecular formula for the compound is CHO2.
