50.0cm3
546.0cm3
659.3cm3
1228.5cm3
Correct answer is D
\(V_2 = \frac{P_1V_1T_2}{T_1P_2} = \frac{114 \times 900 \times 273}{300 \times 76}\)
= 1228.5cm3

79.4cm Hg
74.38cm Hg
74.2cm Hg
69.4cm Hg
Correct answer is B
At 77cm Hg, A.P = \(\frac{75.0 \times 72.0}{72.6} = 74.38\)
1.0000cm3
1.0020cm3
1.0036cm3
1.0180cm3
Correct answer is A
\(V_1 = \frac{V_2}{3} = \frac{1.0018}{3 \times 2.0 \times 10^{-5} \times 30 + 1}\)
= 1cm3
