Question

Green plants use light from the sun to drive photosynthesis. Photosynthesis is a chemical reaction in which water and carbon dioxide chemically react to form the simple sugar glucose and oxygen gas. What mass of carbon dioxide is consumed by the reaction of 9.5g of water?

Answer 1

The mass of carbon dioxide consume is 23.32 g.

Step-by-step explanation:

Given data:

Mass of water = 9.5 g

mass of carbon dioxide = ?

Solution:

Moles of water = mass / molar mass

Moles of water = 9.5 g / 18 g/mol

Moles of water = 0.53 mol

Now we will write the balance chemical equation, and compare the moles of water and carbon dioxide.

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

H₂O : CO₂

6 : 6

0.53 : 0.53

mass of CO₂ = moles × molar mass

mass of CO₂ = 0.53 g× 44 g/mol

mass of CO₂ = 23.32 g
