A) \[\text{6}\text{.023}\times \text{1}{{\text{0}}^{\text{23}}}\text{, 3 and 3}\text{.2}\times \text{1}{{\text{0}}^{\text{23}}}\]
B) \[\text{2, 3}\text{.2}\times \text{1}{{\text{0}}^{\text{23}}}\text{ and 6}\text{.02}\times \text{1}{{\text{0}}^{\text{23}}}\]
C) \[\text{2, 1}\text{.5}\times \text{1}{{\text{0}}^{\text{23}}}\text{ and 1}\text{.2}\times \text{1}{{\text{0}}^{\text{24}}}\]
D) \[\text{1}\text{.2}\times \text{1}{{\text{0}}^{\text{24}}}\text{, 3}\text{.2}\times \text{1}{{\text{0}}^{23}}\text{ and 2}\]
Correct Answer: C
Solution :
No. of moles of S atoms in 0.25 mol of \[{{\text{S}}_{\text{8}}}\]\[=8\times 0.25=2\] No. of sulphur molecules in 0.25 mol of sulphur \[=\text{ }6.023\times {{10}^{23}}\times 0.25=1.506\times {{10}^{23}}\] No. of S atoms in 0.25 mol of \[{{\text{S}}_{\text{8}}}\] \[\text{=1}\text{.506}\times \text{1}{{\text{0}}^{\text{23}}}\times \text{8=1}\text{.205}\times \text{1}{{\text{0}}^{\text{24}}}\]
