Answer:
22.14g of Naâ‚‚O
Explanation:
Equation of reaction
2NaCl + CaO → CaCl₂ + Na₂O
To solve this problem, we'll employ mole concept and see how we can relate 20g of CaO to give us the theoretical yield of Naâ‚‚O.
Molar mass of CaO = (40 + 16) = 56g/mol
Molar mass of Naâ‚‚O = (2*23) + 16 = 62g/mol
From the equation of reaction,
1 mole of CaO = 1 mole of Naâ‚‚O
56g of CaO = 62g of Naâ‚‚O (use number of moles relationship with mass I.e number of moles = mass / molar mass to find the mass).
56g of CaO = 62g of Naâ‚‚O
20g of CaO = y g of Naâ‚‚O
y = (20 * 62) / 56
y = 22.14g of Naâ‚‚O
Therefore, 20g of CaO will produce 22.14g of Naâ‚‚O.
