Calculate molecular diameter (in nanometer) for a gas if its molar excluded volume is $3.2 π ml$ .

Give the answer by multiplying with 100. (Take N_A = 6.0 × 10²³ )

Answer:

20.00

Solution:

$4 N_{A} \frac{4}{3} π r^{3} = 3.2 \times π \times 1 0^{- 6}$

$4 \times 6 \times 1 0^{23} \times \frac{4}{3} π r^{3} = 3.2 π \times 1 0^{- 6}$

$r = 1 0^{- 10} m$

$d = 2 r = 0.2 nm$
