Answer:
0.6 moles of CaO will produced.
Explanation:
Given data:
Mass of calcium = 23.9 g
Moles of CaO produced = ?
Solution:
Chemical equation:
2Ca + O₂ → 2CaO
Number of moles of calcium:
Number of moles = mass/ molar mass
Number of moles = 23.9 g / 40 g/mol
Number of moles = 0.6 mol
Now we will compare the moles of calcium and CaO.
Ca : CaO
2 : 2
0.6 : 0.6
0.6 moles of CaO will produced.

Explanation:
Density: is the ratio between the mass of an object and its volume.
density = mass/ volume. Its units are g/ml, g/cm³ or kg/m³.
What does it tell you about the substance?
Density tells the degree of compactness of a substance. It could tell if the substance is solid or it is porous.
