Calulate the amount of substance io 120g of trioxocarbonate (iv)ion,co2
To calculate the amount of substance in 120g of trioxocarbonate (IV) ion (CO2), you need to use the concept of molar mass and Avogadro's number.
Here's how you can do it step by step:
Step 1: Find the molar mass of CO2
The molar mass refers to the mass of one mole of a substance. To calculate the molar mass of CO2, you need to sum up the atomic masses of carbon (C) and oxygen (O) in the compound.
The atomic mass of carbon (C) is approximately 12.01 g/mol, and the atomic mass of oxygen (O) is approximately 16.00 g/mol. Since CO2 has one carbon and two oxygen atoms, you can calculate the molar mass as follows:
Molar mass of CO2 = (1 * molar mass of C) + (2 * molar mass of O)
= (1 * 12.01 g/mol) + (2 * 16.00 g/mol)
= 12.01 g/mol + 32.00 g/mol
= 44.01 g/mol
Step 2: Use the molar mass to calculate the amount of substance (in moles)
The amount of substance is usually measured in moles. To determine the number of moles present in 120g of CO2, divide the given mass by the molar mass:
Amount of substance (in moles) = mass / molar mass
= 120g / 44.01 g/mol
≈ 2.72 moles
Therefore, the amount of substance in 120g of CO2 is approximately 2.72 moles.
