Calculate the mass of co2 produced when 2ch3oh mixed with o2. Given that 2ch3oh is 4o grams and o2 is 46 grams.
You need to clarify the question. It makes no sense as it stands.
To calculate the mass of CO2 produced when 2CH3OH (methanol) reacts with O2 (oxygen), we need to consider the balanced chemical equation for the reaction.
The balanced equation for the combustion of methanol is:
2CH3OH + 3O2 -> 2CO2 + 4H2O
From the equation, we can see that 2 moles of CH3OH react with 3 moles of O2 to produce 2 moles of CO2.
To calculate the mass of CO2 produced, we can follow these steps:
Step 1: Convert the given mass of CH3OH and O2 to moles using their molar masses.
Molar mass of CH3OH = 4 + (1x4) + 16 = 32 grams/mol
Molar mass of O2 = 16 + 16 = 32 grams/mol
Number of moles of CH3OH = Mass of CH3OH / Molar mass of CH3OH
= 4 grams / 32 grams/mol
= 0.125 mol
Number of moles of O2 = Mass of O2 / Molar mass of O2
= 46 grams / 32 grams/mol
= 1.4375 mol
Step 2: Determine the limiting reactant. The limiting reactant is the reactant that is completely consumed first and determines the maximum amount of product formed.
From the balanced equation, we can see that 2 moles of CH3OH react with 3 moles of O2 to produce 2 moles of CO2. Therefore, the mole ratio between CH3OH and O2 is 2:3.
By comparing the mole ratio to the actual moles of CH3OH and O2, we can see that the O2 is the limiting reactant since there are more moles of O2 (1.4375) than CH3OH (0.125).
Step 3: Calculate the moles of CO2 produced.
According to the balanced equation, 2 moles of CH3OH react to produce 2 moles of CO2. Since O2 is limiting, we can use the mole ratio between CO2 and O2:
Mole ratio of CO2 to O2 = 2/3
Number of moles of CO2 produced = Number of moles of O2 * Mole ratio of CO2 to O2
= 1.4375 mol * (2/3)
= 0.9583 mol
Step 4: Calculate the mass of CO2 produced.
Mass of CO2 produced = Number of moles of CO2 produced * Molar mass of CO2
= 0.9583 mol * 44 grams/mol
≈ 42.1532 grams
Therefore, the mass of CO2 produced when 2CH3OH reacts with O2 is approximately 42.1532 grams.
