To solve this problem, you need to use the balanced equation that relates the reactants and products.
The balanced equation is: C6H12 + 9O2 -> 6CO2 + 6H2O
First, you need to determine the molar ratio between H2O and CO2. From the balanced equation, you can see that for every 6 molecules of CO2 produced, 6 molecules of H2O are also produced. Therefore, the molar ratio is 6:6, or simply 1:1.
To find the number of CO2 molecules formed when 174 molecules of H2O are consumed, you can set up a proportion using the molar ratio:
(174 H2O)/(1 CO2) = (x H2O)/(6 CO2)
Cross-multiplying:
174 H2O = x H2O * 6 CO2
Dividing both sides by 6 CO2:
174 H2O / 6 CO2 = x H2O
Now, you can solve for x, which represents the number of CO2 molecules formed.
x = (174 H2O / 6 CO2) = 29 CO2
Therefore, when 174 molecules of H2O react, 29 molecules of CO2 are formed.
