1.	The number of oxygen atoms present in 14.6 gof magnesium bicarbonate [Mg(HCO3)2) is(1) 6NA (2) 0.6NA(3) NA (4) 0.5 NAPlz explain
Answer» Answer: 2 Explanation: Molecular wt of MAGNESIUM bicarbonate is =146 g So no. Of moles of it=14.6 ➗ 146=0.1 By molecular formula Moles of O atom in 1 MOLE of bicarbonate is 6 Hence no. Of moles of O atom in 0.1mole of bicarbonate is= 0.6 Hence no. Of atom in. 0.6mole O =0.6 NA

Answer»

Answer:

Explanation:

Molecular wt of MAGNESIUM bicarbonate is =146 g

So no. Of moles of it=14.6 ➗ 146=0.1

By molecular formula

Moles of O atom in 1 MOLE of bicarbonate is 6

Hence no. Of moles of O atom in 0.1mole of bicarbonate is= 0.6

Hence no. Of atom in. 0.6mole O =0.6 NA
