Title: how to find the mass of a product given the mass of a reactant in a chemical reaction equation? Post by: tomochita on Sep 9, 2012 Green plants use light from the Sun to drive photosynthesis. Photosynthesis is a chemical reaction in which water (H2O) and carbon dioxide (CO2) chemically react to form the simple sugar glucose (C6H12O6) and oxygen gas (O2).
What mass of oxygen gas is produced by the reaction of 3.04 of carbon dioxide? Round your answer to 3 significant digits. An explanation of how to solve this problem would be appreciated! Title: how to find the mass of a product given the mass of a reactant in a chemical reaction equation? Post by: tomtom1 on Sep 9, 2012 Balanced equation: 6CO2 + 6H2O = C6H12O6 + 6O2
Assuming this is 3.04 g CO2 molar mass CO2 = 12 + 16*2= 44 g/mole moles CO2 = 3.04 g/(44g/mole)=0.0691 mole From balanced equation 1:1 mole ratio for CO2 to O2 so moles O2 = moles CO2 molar mass O2 = 32g/mole 0.0691 mole(32g/mole) = 2.21 g O2 |
