Question

Calculate the number of calcium ions in 1.6 kilograms of calcium phosphate

Answer 1

Answer:

Number of moles of CaO = 5.6g CaO/56.08g per mol = 0.099 mol = 0.1 mol

In 1 mol CaO there are 6.022x1023atoms of Ca ion. So, in 0.1 mol there will be

= 0.1 x 6.022x1023atoms

Hope it helps you

Answer 2

Answer:

0.1*6.022*1023 atom
