What mass of cao will be abtained by heating 3 moles of caco3

Mass = 168.3 g

Explanation:

Given dа ta:

Number of moles of CaCO₃ = 3 mol

Mass of CaO produced = ?

Solution:

Chemical equation:

CaCO₃ → CaO + CO₂

Now we will compare the moles of CaCO₃ with CaO.

CaCO₃ : CaO

1; 1

3 : 3

Mass of CaO:

Mass = number of moles * molar mass

Mass = 3 mol*56.1 g/mol

Mass = 168.3 g
