D) 0.5 mole of $Glucose$	4) 4.5 moles of oxygen atoms

• A. A - 1, B - 2, C - 3, D - 4
• B. A - 4, B - 3, C - 2, D - 1
• C. A - 2, B - 1, C - 3, D - 4
• D. A - 3, B - 1, C - 2, D - 4

Answer 1

Answer: (B)

A - 4, B - 3, C - 2, D - 1

$1$ mole of barium carbonate contains $3$ moles of oxygen atoms. Thus, $1.5$ moles of barium carbonate will contain $4.5$ moles of oxygen atoms.

$1$ mole of sulfuric acid contains $4$ moles of oxygen atoms. Thus, $2$ moles of sulfuric acid will contain $8$ moles of oxygen atoms.

$1$ mole of zinc carbonate contains $3$ moles of oxygen atoms. Thus, $2.5$ moles of zinc carbonate will contain $7.5$ moles of oxygen atoms.

$1$ mole of glucose contains $6$ moles of oxygen atoms. Thus, $0.5$ moles of glucose will contain $3$ moles of oxygen atoms.

So, option ( B ) is correct.
