Question

If one gram of $S$ contains $x$ atoms, atoms is one gram $O$ will be:

• A. $x$
• B. $x/2$
• C. $\frac{2}{3}x$
• D. $2x$

Answer 1

Answer: (D)

$2x$

$1$ gm of $S=\frac{1}{32}$ moles $=x$ atoms

$1$ gm of $O=\frac{1}{16}$ moles

$\therefore$ Atoms in $1$ gm of $O=\frac{x\times \frac{1}{16}}{\frac{1}{32}}=2x$
