To calculate the vapor density of a compound, we need to determine the molar mass of the compound and divide it by the molar mass of hydrogen gas (H₂), which has a vapor density of 2.
The molar mass of carbon dioxide (CO₂) can be calculated as follows:
Carbon (C) molar mass = 12 g/mol
Oxygen (O) molar mass = 16 g/mol
Molar mass of carbon dioxide (CO₂) = (12 g/mol) + 2(16 g/mol) = 12 g/mol + 32 g/mol = 44 g/mol
Now, we can calculate the vapor density of carbon dioxide:
Vapor density = (Molar mass of carbon dioxide) / (Molar mass of hydrogen gas)
Vapor density = 44 g/mol / 2 g/mol = 22
Therefore, the correct option is D. 22
