Question

Green plants use light from the Sun to drive photosynthesis, Photosynthesis is a chemical reaction in which water (H1,0) and carbon dioxide chemically react to form the simple sugar glucose (C11,0.) and oxygen gas (0) What mass of water is consumed by the reaction of 6.2 g of carbon dioxide? Be sure your answer has the correct number of significant digits.

Answer 1

Answer:

2.5 grams of of water is consumed by the reaction of 6.2 g of carbon dioxide.

Explanation:

$6H_2O+6CO_2\rightarrow C_6H_{12}O_6+6O_2$

Moles of carbon dioxide = $\frac{6.2 g}{44 g/mol}=0.1410 mol$

According to reaction , 6 moles of carbon dioxide reacts with 6 moles of water.

Then 0.1410 moles of carbon dioxide will react with:

$\frac{6}{6}\times 0.1410 mol=0.1410 mol$ of water.

Mass of 0.14109 moles of water = 0.1410 mol × 18 g/mol = 2.536 g ≈ 2.5 g

2.5 grams of of water is consumed by the reaction of 6.2 g of carbon dioxide.
