Calulate the amount of substance in 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.
Step 1: Find the molar mass of CO2
The molar mass of carbon (C) is 12.01 g/mol, and the molar mass of oxygen (O) is 16.00 g/mol. Since there are two oxygen atoms in CO2, multiply the molar mass of oxygen by 2.
Molar mass of CO2 = (1 × molar mass of carbon) + (2 × molar mass of oxygen)
= (1 × 12.01) + (2 × 16.00)
= 12.01 + 32.00
= 44.01 g/mol
Step 2: Use the molar mass to calculate the amount of substance (in moles)
The amount of substance (n) is calculated using the formula:
n = mass / molar mass
n = 120g / 44.01 g/mol
n ≈ 2.72 mol
Therefore, there are approximately 2.72 moles of CO2 in 120g of trioxocarbonate (IV) ion.
