Answer 1

Answer:

Option 3 is the true one

Explanation:

1 mole of carbon atoms contains a mass of 12 g. So If you have 6 moles, you have six times the number of particles that are in 12 grams of carbon-12.

1 mol of anything occupies 6.02x10²³ particles (NA)

Answer 2

Answer : The correct option is, You have six times the number of particles that are in 12 grams of carbon-12.

Explanation :

As we are given that the number of moles of substance is, 6 moles.

First we have to calculate the moles of carbon-12.

$\text{Moles of carbon}=\frac{\text{Mass of carbon}}{\text{Molar mass of carbon}}$

Mass of carbon = 12 g

Molar mass of carbon = 12 g/mol

$\text{Moles of carbon}=\frac{12g}{12g/mol}=1mol$

Now we have to calculate the number of particles in 12 g of carbon-12.

1 mole of carbon-12 contains $6.022\times 10^{23}$ number of particles.

Now we have to calculate the number of particles in 6 mole of substance.

As, 1 mole of substance contains $6.022\times 10^{23}$ number of particles.

So, 6 mole of substance contains $6\times 6.022\times 10^{23}$ number of particles.

From this we conclude that, we have six times the number of particles that are in 12 grams of carbon-12.

Hence, the correct option is, You have six times the number of particles that are in 12 grams of carbon-12.
