Question

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

Answer 1

Mass = 168.3 g

Step-by-step explanation:

Given data:

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
