It seems like you're providing information about the molar masses (molar weights) of different substances and asking for the molar volume of carbon dioxide (V(CO2)). However, the information you provided is a bit unclear. Typically, when dealing with chemical equations and stoichiometry, we use molar masses to convert between mass and moles, and then use the coefficients in the balanced chemical equation to find the relationship between different substances.

If you have a chemical equation for the reaction involving carbon (C), water (H2O), and carbon dioxide (CO2), and you're given the masses of carbon (C) and water (H2O), you can use stoichiometry to find the moles of each substance involved. Once you have the moles, you can use the ideal gas law to find the volume of carbon dioxide.

The ideal gas law is given by:

$PV = nRT$

where:

• $P$ is the pressure of the gas,
• $V$ is the volume of the gas,
• $n$ is the number of moles of gas,
• $R$ is the ideal gas constant,
• $T$ is the temperature.

If you're working under standard conditions (STP), the molar volume of an ideal gas is approximately 22.4 liters/mol.

Please provide more details or the chemical equation so I can assist you further.
