Calculate total number of SO2 molecules in a sample hating 32 milligrams of the SO2 gas, 1.4×1020 number of SO2 molecules, 0 .8 ml of SO2 gas at 6 atm and 300 K.[ Given : NA=6×1023,R=0.08atmL/mol K](Express your answer in terms of multiple of 1020 ano then round off to nearest integer for e.g. if your answer is 6.2×1020 fill 6 in O:MR after rounding off.]

Total number of sulfur dioxide molecule in the solution,10−3×3264×6×1023+1.4×1020+6×0.8×10−30.08×300×6×1023=5.6×1020⇒Ans. = 6

Detailed Solution

Total number of sulfur dioxide molecule in the solution,

$10^{- 3} \times \frac{32}{64} \times 6 \times 10^{23} + 1.4 \times 10^{20}$

$+ \frac{6 \times 0.8 \times 10^{- 3}}{0.08 \times 300} \times 6 \times 10^{23} = 5.6 \times 10^{20}$

$\Rightarrow$ Ans. = 6
