A) 736.18mm
B) 820.20mm
C) 784.15mm
D) 857.14mm
Correct Answer: D
Solution :
Key Idea: Use Boyles law to find the pressure of gas. \[{{P}_{1}}{{V}_{1}}={{P}_{2}}{{V}_{2}}\] (Boyles law) Given, \[{{P}_{1}}=720\,mm,\,\,{{P}_{2}}=?\] \[{{V}_{1}}=100\,mL,\,{{V}_{2}}=84\,mL\] \[{{P}_{1}}{{V}_{1}}={{P}_{2}}{{V}_{2}}\] or \[{{P}_{2}}=\frac{{{P}_{1}}{{V}_{1}}}{{{V}_{2}}}\] \[=\frac{720\times 100}{84}\] = 857.14 mm
