Chemistry

Answer : The correct option is A.

Explanation :

One mole of substance means the amount of substance that contains as many particles in pure substance. So, one mole contains $6.02\times 10^{23}$ of particles. And this is also known as Avogadro's number.

Molar mass of carbon = 12 g/mole

Molar mass of oxygen = 16 g/mole

Moles of carbon-12 = $\frac{\text{ Mass of carbon-12}}{\text{ Molar mass of carbon-12}}=\frac{12g}{12g/mole}=1mole$

Moles of carbon-12 = $\frac{\text{ Mass of carbon-12}}{\text{ Molar mass of carbon-12}}=\frac{14g}{12g/mole}=1.167mole$

Moles of oxygen = $\frac{\text{ Mass of oxygen}}{\text{ Molar mass of oxygen}}=\frac{12g}{16g/mole}=0.75mole$

Moles of oxygen = $\frac{\text{ Mass of oxygen}}{\text{ Molar mass of oxygen}}=\frac{14g}{16g/mole}=0.875mole$

Therefore, the only option A which contain 1 mole.
