Given information:
- Mass of hydrocarbon = 10g
- Mass of oxygen required for complete combustion = 40g
- Product formed: CO2 and water
- Absorption of CO2 in lime water leads to a mass increase of 27.5g
Calculating the mass of water formed:
1. Balance the chemical equation:
Assume the hydrocarbon is CxHy.
The balanced equation for complete combustion is:
CxHy + (x + y/4)O2 -> xCO2 + (y/2)H2O
2. Calculate moles of hydrocarbon and oxygen:
Moles of hydrocarbon = 10g / molar mass of hydrocarbon
Moles of oxygen = 40g / molar mass of oxygen
3. Calculate moles of water formed:
From the balanced equation, 1 mole of hydrocarbon produces y/2 moles of water.
Therefore, moles of water = (y/2) * moles of hydrocarbon
4. Calculate mass of water formed:
Mass of water = Moles of water * molar mass of water
5. Check the mass increase due to CO2 absorption:
The mass increase due to CO2 absorption is 27.5g.
This mass increase is equivalent to the mass of CO2 absorbed.
6. Calculate the moles of CO2 absorbed:
Moles of CO2 = 27.5g / molar mass of CO2
7. Convert moles of CO2 absorbed to moles of water formed:
From the balanced equation, 1 mole of CO2 corresponds to (y/2) moles of water.
8. Calculate the mass of water formed:
Mass of water = Moles of water * molar mass of water
Therefore, by following the steps above and using the given information, the mass of water formed during the combustion of the hydrocarbon can be accurately calculated.
- Mass of hydrocarbon = 10g
- Mass of oxygen required for complete combustion = 40g
- Product formed: CO2 and water
- Absorption of CO2 in lime water leads to a mass increase of 27.5g
Calculating the mass of water formed:
1. Balance the chemical equation:
Assume the hydrocarbon is CxHy.
The balanced equation for complete combustion is:
CxHy + (x + y/4)O2 -> xCO2 + (y/2)H2O
2. Calculate moles of hydrocarbon and oxygen:
Moles of hydrocarbon = 10g / molar mass of hydrocarbon
Moles of oxygen = 40g / molar mass of oxygen
3. Calculate moles of water formed:
From the balanced equation, 1 mole of hydrocarbon produces y/2 moles of water.
Therefore, moles of water = (y/2) * moles of hydrocarbon
4. Calculate mass of water formed:
Mass of water = Moles of water * molar mass of water
5. Check the mass increase due to CO2 absorption:
The mass increase due to CO2 absorption is 27.5g.
This mass increase is equivalent to the mass of CO2 absorbed.
6. Calculate the moles of CO2 absorbed:
Moles of CO2 = 27.5g / molar mass of CO2
7. Convert moles of CO2 absorbed to moles of water formed:
From the balanced equation, 1 mole of CO2 corresponds to (y/2) moles of water.
8. Calculate the mass of water formed:
Mass of water = Moles of water * molar mass of water
Therefore, by following the steps above and using the given information, the mass of water formed during the combustion of the hydrocarbon can be accurately calculated.
