To determine the number of methanol molecules (CH3OH) that must react if exactly 1802 molecules react, we need to establish the stoichiometry of the reaction.
From the balanced equation provided earlier, we know that:
2CO(g) + 2H2(g) → CH3OH(l) + CO2(g)
This equation indicates that 2 molecules of CO react with 2 molecules of H2 to produce 1 molecule of CH3OH.
Therefore, the molar ratio of CO to CH3OH is 2:1.
If exactly 1802 molecules of CO react, then the number of methanol molecules that must also react can be determined using this ratio.
1802 molecules of CO corresponds to 1802 / 2 = 901 molecules of CH3OH.
So, 901 methanol molecules must also react if exactly 1802 molecules react.
