34g Al(HCO3)3 gives 34/210 moles = 0.1619 moles

0.1619 moles Al(HCO3)3 has 3*0.1619 = 0.4857 moles  HCO3-

0.1619 moles Al(HCO3)3 has 0.1619 moles aluminium ions

0.1619 moles Al(HCO3)3 has 9*0.1619 moles oxygen = 1.4571 moles oxygen

what are moles?

In chemistry, a mole, sometimes spelled mol, is a common scientific measurement unit for significant amounts of very small objects like atoms, molecules, or other predetermined particles. The mole designates 6.02214076 10 23 units, which is a very huge number.

Aluminium bicarbonate has a formula of Al(HCO3)3 and it molecular weight is 210g.

1 mole HCO3- weighs 61 g

1 mole Al(HCO3)3 has 3 moles of  HCO3-

210 g Al(HCO3)3  gives 1 mole

Thus, 34g Al(HCO3)3 gives 34/210 moles = 0.1619 moles

1 mole HCO3- weighs 61 g

1 mole Al(HCO3)3 has 3 moles of  HCO3-
