Question

How many moles of water molecules are required to produce 5.60mole of calcium hydroxide by reaction of calcium oxide and water?.

Answer 1

Answer:

mark me as brainlist

Explanation:

Thus the number of molecules in 16 gm or 0.5 mole of oxygen gas are 0.5 x 6.023 x 10^(23) = 3.012 x 10^(23) molecules. Similarly, 16 gm of elemental oxygen (represented as O) would contain 1 mole of atoms, since the atomic mass of oxygen is 16 and hence will have 6.023 x 10^23 atoms.
