Question

A pre-weighed vessel was filled with oxygen at N.T.P. and weighted. It was then evacuated, filled with $\mathrm { SO } _ { 2 }$ at the same temperature and pressure, and again weighted. The weight of oxygen will be.

• A. The same as that of $\mathrm { SO } _ { 2 }$
• B. $\frac { 1 } { 2 }$that of$\mathrm { SO } _ { 2 }$
• C. Twice that of$\mathrm { SO } _ { 2 }$
• D. One fourth that of$\mathrm { SO } _ { 2 }$

Answer 1

Answer: (B)

$\frac { 1 } { 2 }$that of$\mathrm { SO } _ { 2 }$

Answer 2

The weight of oxygen will be $\frac { 1 } { 2 }$that of $\mathrm { SO } _ { 2 }$
