A) 76.34 cm Hg
B) 82.40 cm Hg
C) 94.24 cm Hg
D) 104.34 cm Hg
Correct Answer: A
Solution :
[a] For tiny glass tube, \[{{P}_{1}}{{V}_{1}}={{P}_{2}}{{V}_{2}}\] \[\therefore {{P}_{2}}=\frac{{{P}_{1}}{{V}_{1}}}{{{V}_{2}}}=\frac{4.5\times 0.50}{500}=0.0045\,\,atm.\] Thus \[P=\text{1}\,atm+0.0045\,atm\] \[=1.0045atm=76.34\text{ cm of }Hg.\]You need to login to perform this action.
