Question

Given. 0.25 mole of S8 molecules. Calculate
1. The number of S8 molecules
2.The number of S atoms
3. The number of moles of S atoms

Answer 1

Answer:

1mol=6.022×10^23

1.(0.25)(6.022×10^23)

=1.51×10^24

2.(1.51×10^24)(6.022×10^23)

=1.20×10^24

3.(1.20×10^24)/(6.022×10^23)

=2.0 mol

Answer 2

For 1: Number of $S_8$ molecules = $1.506\times 10^{23}$

For 2: Number of S-atoms = $1.204\times 10^{24}$

For 3: Moles of S-atoms = 2.0 moles

Explanation:

We are given:

Moles of $S_8$ = 0.25 moles

1 mole of $S_8$ molecule contains 8 moles of sulfur atoms

According to mole concept:

1 mole of a compound contains $6.022\times 10^{23}$ number of particles

• For 1:

So, 0.25 moles of $S_8$ compound will contain = $(0.25\times 6.022\times 10^{23})=1.506\times 10^{23}$ number of molecules

• For 2:

So, 0.25 moles of $S_8$ compound will contain = $(8\times 0.25\times 6.022\times 10^{23})=1.204\times 10^{24}$ number of sulfur atoms

• For 3:

Moles of sulfur atoms = (8 × 0.25) = 2.0 moles
