Question

Mass-mass problem:

If 25.0 grams of carbon dioxide are used in photosynthesis how many grams of glucose (C6H12O6) could be Produced according
to the following equation : 6CO2 + 6H2O → C6H12O6 + 602

Answer 1

17.05 g of glucose

Step-by-step explanation:

The equation of the reaction is given as;

6CO2 + 6H2O → C6H12O6 + 602

From the equation;

6 mol of CO2 produces 1 mol of C6H12O6

Converting to masses;

CO2:

Mass =Number of moles * Molar mass

Mass = 6 mol * 44 g/mol = 264 g

C6H12O6:

Mass = Number of moles * Molar mass

Mass = 1 mol * 180 g/mol = 180 g

This means 264g of CO2 produces 180g of C6H12O6

25g of CO2 would produce x g of C6H12O6

264 = 180

25 = x

x = 25 * 180 / 264

x = 17.05 g
