Question

The chemical formula for glucose is C6H12O6. Six molecules of carbon dioxide (CO2) react with six molecules of water (H2O) to form six molecules of oxygen (O2). How many molecules of glucose will be produced?

A 1
B 6
C 12
D 36

can anyone help me figure this out ? thanks.

Answer 1

6CO2 + 6H2O --> 6O2 + C6H12O6
Look at the formula. It tells you 1 molecule of glucose is formed. By the way, the formula I wrote does NOT mean molecules but moles (1 mole = 6.022 x 10^23 molecules). However, for your problem that doesn't make any difference.

Answer 2

i get how the formula works, kinda. thank you !
