Question

How many grams of glucose are produced from 10.3 g of CO2

Answer 1

There are produced 6.72 g

Step-by-step explanation:

This is the reaction:

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

1 mol of glucose reacts with 6 moles of oxygen, to make 6 moles of dioxide and 6 moles of water

Molar mass of CO₂ = 46 g/m

Moles CO₂ = 10.3 g/ 46g/m = 0.224 moles

Ratio is 6:1

6 moles of CO₂ are made from 1 mol of glucose

0.224 moles of CO₂ are made from (0.224 . 1)/6 = 0.0373 moles of glucose

Molar mass glucose = 180.15 g/m

Mass glucose = moles . molar mass

0.0373 m . 180.15 g/m = 6.72 g
