A) 31842 kg
B) 58.55 kg
C) 342.58 kg
D) None of these
Correct Answer: B
Solution :
\[w=-nRT\,\,In\frac{{{P}_{1}}}{{{P}_{2}}}\] |
\[=-\,10\,\,\times \,\,8.314\,\,\times \,\,300\,\,In\frac{10}{1}\] |
\[=-\,57441.42\,J\] |
\[w=-\,mgh\] |
\[\therefore m\,\,\times \,\,9.81\,\,\times \,\,100=57441.42\] |
\[m=58.55\,kg\] |
