3.2 g of CHOH burns completely in excess oxygen. What mass of carbon dioxide is produced? (H = 1, C = 12, O = 16)
Answer and explanation
Correct answer: A. 4.4 g
- Step 1: Molar mass of CHOH g/mol, so moles mol.
- Step 2: Each mole gives 1 mol of CO, i.e. g.
Answer
4.4 g.
Why not the others: 3.6 g: that is the mass of the other product. 8.8 g: it doubles the correct value. 3.2 g: the mass of fuel is repeated.
