A manometer contains a liquid of density $$5.44$$ $$g/cm$$ is attached to a flask containing gas 'A as follows If the same liquid is used in barometer to measure the atmospheric pressure, then what will be the length of the liquid column, which exerts pressure equal to $$1$$ atm ? (density$$ of Hg $$=$$ $$13.6$$ $$g/cm3)The$$ initial pressure of gas A in the flask is:If gas A undergoes $$30$$% trimerization $$3A(g)⇌$$A3(g)$$ then the difference in height of the liquid level in two columns is:
