How many moles of CaO will be produced from 23.9 g of Ca?

2Ca (s) + O2 (g) - 20:0 (3)

mol

0.6 moles of CaO will produced.

Explanation:

Given dа ta:

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.
