The mass of carbon monoxide, CO needed for the reaction is 15.4 g
Balanced equation
2CO + O₂ —> 2CO₂ ΔH = –566 KJ
From the balanced equation above,
566 KJ of heat was released by 2 moles of CO.
Therefore,
155 KJ of heat will be released by = (155 × 2) / 566 = 0.55 mole of CO
How to determine the mass of CO
- Mole of CO = 0.55 mole
- Molar mass of CO = 12 + 16 = 28 g/mol
Mass = mole × molar mass
Mass of CO = 0.55 × 28
Mass of CO = 15.4 g
