Question

The number of oxygen atoms present in 14.6 g of magnesium bicarbonate is

Answer 1

Answer:

Explanation:

ANSWER

weight of magnesium bicarbonate = 14.6 g

molecular mass of magnesium bicarbonate = 146 g  

no. of moles =  

146

14.6

​  

 = 0.1

in 1 mole of magnesium bicarbonate moles of oxygen atom = 6

in 0.1 moles of magnesium bicarbonate moles of oxygen atom = 0.6 mole

so, no. ofoxygen atom present = 0.6 N
