Question

How to calculate the number of carbon atoms present in 2 moles of carbon?

Answer 1

Answer:

2 × 6.02 ×10^23 =12.04 x 10^23

Explanation:

One mole of any substance has 6.02 x 10^23 particles (atoms,formula units,ions or molecules)

it is

●ion for ionic substance (such as 2 moles of Na+)

●atoms for substance in elemental/atomic form (such as 2 mole of hydrogen,2 mole of carbon)

●molecules of compounds (such as in HCl hydrochloric acid)

●formula units for ionic compound (e.g NaCl)

the formula for number of particles (in our case particles mean atoms in 2 moles of C)is:

no. of particles=no. of moles×Avogadro's number

here Avogadro's number has constant value of 6.02x10^23.

so according to this formula,

no. of C atoms=no. of moles of C x Avogadro's number

no. of C atoms=2x6.02x10^23

no. of C atoms=12.04x10^23 OR 1.204x10^24

Answer 2

Explanation:

two moles of carbon atoms contains 2 times 6.02 x 1023 atoms, which equals 12.04 x 1023 atoms, which can be written as 1.204 x 1024 atoms.
