Consider again the reaction for photosynthesis: 6CO2 + 6H2O → C6H12O6 + 6O2

What mass of water is required to react completely with 157.35 g CO2? (Molar mass of H2O = 18.02 g/mol; molar mass of CO2 = 44.01 g/mol)

157.35 g CO2 =
g H2O

Mass of water required = 64.42 g

Given

Reaction

6CO2 + 6H2O → C6H12O6 + 6O2

157.35 g CO2

Required

mass of water

Solution

mol CO₂ = mass : MW CO₂

mol CO₂ = 157.35 g : 44.01 g/mol

mol CO₂ = 3.575

From the equation, mol ratio CO₂ : H₂O = 6 : 6, so mol H₂O = mol CO₂=3.575

Mass H₂O = mol x MW H₂O

mass H₂O = 3.575 x 18.02

mass H₂O = 64.42 g

An element would be fire, earth, water, or air. An atom would be everything we are made of

Explanation:

Fun fact: atoms never touch each other. Slap a kid technically you didn't even do it lol just kidding don't do that... without me. Have a blessed day!
