According to the balanced equation 6 moles of carbon dioxide will react with 6 moles of water to produce 1 mole of sugar and 6 moles of oxygen.
What are the molar masses of the following compounds from the photosynthesis equation?
CO2=___________g=1 mole
H20=___________g=1 mole
C6H12O6=________g=1 mole
O2=________g=1 mole ??
Look at the periodic table and add up the atomic masses. For example,
CO2 is 44.
C = 12; O = 16 x 2 = 32 and 32 + 12 = 44
I have rounded the numbers. Use the number of significant figures you need when you do it yourself. CO2 would be 44.01 if you wanted more accuracy.
To determine the molar masses of the compounds given in the photosynthesis equation, we need to refer to the periodic table for the atomic masses of the elements involved. Here's how to calculate them:
1. CO2 (carbon dioxide):
To calculate the molar mass of CO2, we sum up the atomic masses of its constituent atoms, which are carbon (C) and oxygen (O).
C: atomic mass = 12.01 g/mol (from the periodic table)
O: atomic mass = 16.00 g/mol (from the periodic table)
Molar mass of CO2 = (12.01 g/mol × 1 C) + (16.00 g/mol × 2 O) = 12.01 g/mol + 32.00 g/mol = 44.01 g/mol
So, the molar mass of CO2 is 44.01 g/mol.
2. H2O (water):
To calculate the molar mass of H2O, we sum up the atomic masses of its constituent atoms, which are hydrogen (H) and oxygen (O).
H: atomic mass = 1.01 g/mol (from the periodic table)
O: atomic mass = 16.00 g/mol (from the periodic table)
Molar mass of H2O = (1.01 g/mol × 2 H) + (16.00 g/mol × 1 O) = 2.02 g/mol + 16.00 g/mol = 18.02 g/mol
So, the molar mass of H2O is 18.02 g/mol.
3. C6H12O6 (sugar, specifically glucose):
To calculate the molar mass of C6H12O6, we sum up the atomic masses of its constituent atoms, which are carbon (C), hydrogen (H), and oxygen (O).
C: atomic mass = 12.01 g/mol (from the periodic table)
H: atomic mass = 1.01 g/mol (from the periodic table)
O: atomic mass = 16.00 g/mol (from the periodic table)
Molar mass of C6H12O6 = (12.01 g/mol × 6 C) + (1.01 g/mol × 12 H) + (16.00 g/mol × 6 O) = 72.06 g/mol + 12.12 g/mol + 96.00 g/mol = 180.18 g/mol
So, the molar mass of C6H12O6 is 180.18 g/mol.
4. O2 (oxygen gas):
To calculate the molar mass of O2, we sum up the atomic masses of its constituent atoms, which are oxygen (O).
O: atomic mass = 16.00 g/mol (from the periodic table)
Molar mass of O2 = (16.00 g/mol × 2 O) = 32.00 g/mol
So, the molar mass of O2 is 32.00 g/mol.
