*🕹️Mole concept MCQs*

🧿If 12 gram of carbon has x atoms, then the number of atoms in 12 grams of magnesium will be:
a) x
b) 2x
c) x/2
d) 1.5 x

🧿Which of the following correctly represents
360 gram of water ?
i 2 moles of H, ii) 20 moles of water iii) 6.022 × 1023 molecules of water
iv) 1.2044 × 1025 molecules of water
(i) Only
(i) and (iv)
(ii) and (iii)
(ii) and (iv)


🧿THE MASS OF ONE MOLECULE OF A SUBSTANCE IS 4.65 * 10-23 G. WHAT IS ITS MOLECULAR MASS ? WHAT COULD THIS SUBSTANCE BE ?

🧿THE MASS OF ONE MOLECULE OF A SUBSTANCE IS 5.3138 * 10-23 G. WHAT IS ITS MOLECULAR MASS ? WHAT COULD THIS SUBSTANCE BE ?


🧿WHICH CONTAINS MORE MOLECULES, 10 G OF SULPHUR DIOXIDE (SO2) OR 10 G OF
OXYGEN (O2) ? (ATOMIC MASSES : S = 32 U ;
0 = 16 U)
3
Here are the correct answers with short explanations 👇



🧿 Q1. If 12 gram of carbon has x atoms, then the number of atoms in 12 grams of magnesium will be:
• Atomic mass of C = 12 u → 12 g = 1 mole
• Atomic mass of Mg = 24 u → 12 g = 0.5 mole

So, atoms in 12 g Mg = ½ of x

Correct answer: (c) x/2



🧿 Q2. Which of the following correctly represents 360 g of water?
• Molar mass of H₂O = 18 g/mol
• 360 g ÷ 18 g/mol = 20 moles of water

Now check statements:

i) 2 moles of H → incorrect
ii) 20 moles of water → correct
iii) 6.022 × 10²³ molecules → (that is 1 mole)
iv) 20 × 6.022 × 10²³ = 1.2044 × 10²⁵ molecules correct

Correct answer: (ii) and (iv)



🧿 Q3. Mass of one molecule = 4.65 × 10⁻²³ g

Find molecular mass & substance

Molecular mass =
4.65 × 10^{-23} × 6.022 × 10^{23}

= 28 g/mol

A substance with molecular mass 28 is Nitrogen (N₂)

Answer:
• Molecular mass = 28 g/mol
• Substance = Nitrogen (N₂)



🧿 Q4. Mass of one molecule = 5.3138 × 10⁻²³ g

Molecular mass =
5.3138 × 10^{-23} × 6.022 × 10^{23}

= 32 g/mol

A substance with molecular mass 32 is Oxygen (O₂)

Answer:
• Molecular mass = 32 g/mol
• Substance = Oxygen (O₂)



🧿 Q5. Which contains more molecules:

10 g SO₂ or 10 g O₂ ?
• Molar mass of SO₂ = 32 + (16×2) = 64 g/mol
• Moles of SO₂ = 10/64 = 0.15625 mol
• Molar mass of O₂ = 32 g/mol
• Moles of O₂ = 10/32 = 0.3125 mol

More moles = more molecules

Correct answer: 10 g of Oxygen (O₂)
