Calculate the number of grams of CO2 is produced from 58.0g of glucose?
______g. CO2
To calculate the number of grams of CO2 produced from a given amount of glucose, we need to use the balanced chemical equation for the combustion of glucose. The chemical equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
From the equation, we can see that 1 mole of glucose (C6H12O6) reacts to produce 6 moles of CO2 (carbon dioxide). We need to convert the mass of glucose (58.0g) to moles and then use the stoichiometry of the balanced equation to find the mass of CO2 produced.
Here's how to calculate it step by step:
Step 1: Find the molar mass of glucose (C6H12O6).
The molecular formula of glucose (C6H12O6) indicates that it contains 6 carbon atoms (C), 12 hydrogen atoms (H), and 6 oxygen atoms (O).
The atomic masses are:
Carbon (C) = 12.011 g/mol
Hydrogen (H) = 1.008 g/mol
Oxygen (O) = 15.999 g/mol
To find the molar mass of glucose, multiply the atomic mass of each element by the number of atoms present, and add them up.
Molar mass of glucose = (6 * 12.011 g/mol) + (12 * 1.008 g/mol) + (6 * 15.999 g/mol)
Step 2: Calculate the number of moles of glucose.
To find the number of moles, divide the mass of glucose (58.0g) by its molar mass calculated in Step 1.
Number of moles = Mass of glucose / Molar mass of glucose
Step 3: Use the stoichiometry of the balanced chemical equation to find the number of moles of CO2 produced.
From the balanced equation, we know that 1 mole of glucose produces 6 moles of CO2. Therefore, the number of moles of CO2 produced is equal to the number of moles of glucose multiplied by the stoichiometric ratio.
Number of moles of CO2 = Number of moles of glucose * 6
Step 4: Calculate the mass of CO2 produced.
To find the mass of CO2 produced, multiply the number of moles of CO2 by its molar mass.
Mass of CO2 = Number of moles of CO2 * Molar mass of CO2
Finally, substitute the values into the equation:
Mass of CO2 = (Number of moles of glucose * 6) * Molar mass of CO2
By calculating these values, you will be able to determine the number of grams of CO2 produced from 58.0g of glucose.
