The L.C.M.of 3,2.7 and 0.09 is (a) 2.70.27, (c) 0.027

Find the vlaue of 27xx1.bar( 2) xx 5.526bar(2) xx 0.bar( 6) .

The density of a gas at 27^(@)C and 1 bar pressure is "2.56 g L"^(-1) . Calculate the molar mass.

9 xx 10^(22) atoms of Ar and n moles of O_(2) are kept in a vessel of capacity 5L at 1 atm and 27^(@)C . (Consider N_(A)=6 xx 10^(23), R=0.0821 L atm "mol"^(-1)K^(-1)) : If all the O_(2) in vessel , then:
