if the fuel has a density of 0.626 g/mL, how many grams of H2O and CO2 is produced in burning 2 liters of the fuel?
depends. what is the combustion reaction?
Klasmeyt may sagot ka na dyan? naghahanap din po ako eh.. need help po :)
To determine the number of grams of H2O and CO2 produced in burning 2 liters of the fuel, we first need to calculate the mass of the fuel burned.
Given the density of the fuel is 0.626 g/mL, we can convert the volume of fuel from liters to milliliters using the conversion factor: 1 L = 1000 mL.
So, 2 liters of fuel is equivalent to 2 * 1000 = 2000 mL of fuel.
To find the mass of the fuel, we multiply the volume (in milliliters) by the density:
Mass of fuel = Volume of fuel * Density of fuel
= 2000 mL * 0.626 g/mL
= 1252 grams
Now, we need to understand the balanced chemical equation for burning the fuel to determine the ratio of H2O and CO2 produced. For the sake of explanation, let's say the balanced chemical equation is:
CnHm + (n + m/4)O2 -> nCO2 + m/2H2O
Where n and m are the coefficients of C and H respectively.
Next, we need to determine the coefficients n and m specific to the fuel being burned. However, since you haven't provided any information about the composition of the fuel, we cannot calculate the exact values. Hence, I will provide an example to illustrate the calculation process.
Assuming the balanced chemical equation for the fuel combustion is:
2C2H6 + 7O2 -> 4CO2 + 6H2O
We can see that for every 2 moles of C2H6 burned, we produce 4 moles of CO2 and 6 moles of H2O. Therefore, the ratio is:
4 moles of CO2 : 6 moles of H2O
We can convert moles to grams using the molar mass of CO2 and H2O. The molar mass of CO2 is 44 g/mol, and the molar mass of H2O is 18 g/mol.
So, for every 44 grams of CO2 produced, 6 * 18 = 108 grams of H2O is produced.
Finally, we can calculate the mass of CO2 and H2O produced from the mass of the fuel:
Mass of CO2 = Mass of fuel * (Moles of CO2 / Moles of C2H6) * Molar mass of CO2
Mass of H2O = Mass of fuel * (Moles of H2O / Moles of C2H6) * Molar mass of H2O
Substituting the example values:
Mass of CO2 = 1252 g * (4/2) * 44 g/mol
Mass of H2O = 1252 g * (6/2) * 18 g/mol
Please note that the values of moles and molar masses will differ depending on the specific fuel being burned.
