2 gm of O2O_{2}gas is taken at 27°C and pressure 76 cm. Of Hg. Then find out volume of gas (in litre)

A

1.53

B

2.44

C

3.08

D

44.2

Answer

1.53

Explanation

Solution

PV=μRT=mMRTPV = \mu RT = \frac{m}{M}RTŽV=mRTMPV = \frac{mRT}{MP}

=2×10−3×8.3×30032×10−3×105= \frac{2 \times 10^{- 3} \times 8.3 \times 300}{32 \times 10^{- 3} \times 10^{5}}=1.53×10−3m31.53 \times 10^{- 3}m^{3}= 1.53 litre
