Question

A giant molecule contains 0.25% of a metal whose atomic weight is 59. Its molecule contains one atom of that metal. Its minimum molecular weight is :

• A. $5900$
• B. $23600$
• C. $11800$
• D. $\frac{100\times 59}{0.4}$

Answer 1

The correct option is B $23600$

Suppose the molecular mass of molecular $x$ and no of metal present in molecular be $n$

$\frac{x\times 0.25}{100}=59n$

$\frac{x}{400}=59n$

$x=400\times 59n$

$x=23600n$

so minimum molecular weight be 23600
