Cell respiration glucose is reacted wth oxygen in body to produce carbon dioxide and water how many liters of carbon dioxide would be produced if 90.0 g of glucose completely reacts with oxygen
C6H12O6(s)+ 6O2(g) -> 6H2O(g) + 6CO2 (g)
How many liters of carbon dioxide would be produced if 90.0 g of glucose completely reacts with oxygen
1. mols glucose = grams/molar mass
2. Using the coefficients in the balanced equation, convert mols glucose to mols CO2.
3. Now convert mols CO2 to L. L CO2 = mols CO2 x 22.4 L/mol = ?
To determine the number of liters of carbon dioxide produced when 90.0 g of glucose completely reacts with oxygen, you will need to perform the following steps:
Step 1: Calculate the number of moles of glucose (C6H12O6):
To do this, divide the given mass of glucose by its molar mass. The molar mass of glucose (C6H12O6) is calculated by adding up the atomic masses of each element: C (12.01 g/mol) x 6 + H (1.01 g/mol) x 12 + O (16.00 g/mol) x 6.
Molar mass of glucose = (12.01 g/mol x 6) + (1.01 g/mol x 12) + (16.00 g/mol x 6) = 180.18 g/mol
Number of moles of glucose = Mass of glucose (in grams) / Molar mass of glucose
Step 2: Calculate the number of moles of carbon dioxide (CO2):
According to the balanced equation, for every 1 mole of glucose reacted, 6 moles of carbon dioxide are produced.
Number of moles of CO2 = Number of moles of glucose x 6
Step 3: Calculate the volume of carbon dioxide gas:
Since the volume of a gas relates directly to the number of moles, you can use the ideal gas law equation: PV = nRT (P = pressure, V = volume, n = number of moles, R = gas constant, T = temperature).
To perform this calculation, you need to know the pressure, temperature, and volume conditions. If those are not provided, you can assume standard temperature and pressure (STP), which is typically 0 °C (273.15 K) and 1 atmosphere (atm) pressure.
At STP conditions, 1 mole of any ideal gas occupies 22.414 liters of volume.
Number of liters of carbon dioxide = Number of moles of CO2 x 22.414 L/mol
By following these steps, you can determine the number of liters of carbon dioxide produced when 90.0 g of glucose completely reacts with oxygen.
