Answer: mass of magnesium contains number same number of molecules as a present in 6.4g of oxygen is 9.72 grams

Explanation:

No of moles of oxygen = 6.4/16 (mass of element/molecular mass)= 0.4

No of moles of oxygen = No of moles of Magnesium (Since no molecules are said to be the same)

Hence mass of magnesium = Moles of Mg x Molecular mass of Mg = 0.4 x 24.3 = 9.72 grams

The mass of magnesium contains number same number of molecules as a present in 6.4g of oxygen is 9.72 grams
