Question

no. o2 atoms in 60gm of glucose

Answer 1

1/3 mole glucose have 1/3×NA×3=NA

Hope it helps

Answer 2

$\textbf{ANSWER}$

_____________________

$\textbf{GIVEN}$

Mass of glucose =60g

Moles of glucose = mass/molar mass

Moles of glucose = 60/180

Moles of glucose = 0.33mol

Now

Number of atoms of Oxygen = Number of atoms of oxygen in one molecule of Glucose × Moles of glucose × Avagadro number

Number of atoms of oxygen = 6 × 0.33×6.023×10^23

Number of atoms of oxygen= 11.9×10^23

Number of atoms of oxygen = 12×10^23
