Question

The density of mercury is $13.6g/c{m}^3$.Estimate the b value.Atomic mass of Hg=200.

• A. $29.41c{m}^3$
• B. $58.82c{m}^3$
• C. $98.82c{m}^3$
• D. Non eof these

Answer 1

The correct option is B $58.82c{m}^3$

$r^3=\frac{3M}{4\pi d{N}_A}=\frac{3\times 200}{4\times 3.1416\times 13.6\times 6.023\times {10}^{23}}=5.83\times {10}^{-24}$
$b=\frac{4}{3}\pi r^3\times 4N_A=\frac{4}{3}\times 3.1416\times 5.8\times {10}^{-24}\times 4\times 6.023\times {10}^{23}=58.8/cm$
