The density of ironis 7.8 g/c.c and that of mercury is 13.6 g/c.c. Therefore, an iron block will float on mercury.

At 5xx10^(5) bar pressure density of diamond and graphite are 3 g//c c and 2g//c c respectively, at certain temperature 'T' .Find the value of DeltaU-DeltaH for the conversion of 1 mole of graphite to 1 mole of diamond at temperature 'T' :

The density of apure substance 'A' whose atoms are in cubic close pack arragement is 1 g//c c . If the all the tetrahedral voids are occupied by 'B' atom , What is the density of resulting solid in g//c c .[ "Atomic mass" = (A)= 30 g//"mol" and atomic mass (B)= 50 g//"mol" ]

Percentage of (G+C) is

Calculate r.m.s velocity of nitrogen molecules at 27^@C and 76 cm of mercury pressure.

The vapour pressure of an aqueous solution of glucose is 750 mm of mercury at 100^@ C . Mole fraction of solute will be

CdO has NaCl like structure with density 8.27g//c c . If the ionic-radius of O^(2-) is 1.24A^(@) determine the ionic radius of Cd^(2+) :

Mercury has an angle of contact equal to 140^@ with soda lime glass. A narrow tube of radius 1.00 mm made of this glass is dipped in a trough containing mercury. By what amount does the mercury dip down in the tube relative to the liquid surface outside ? Surface tension of mercury at the temperature of the experiment is 0.465 N m^-1 . Density of mercury = 13.6xx 10^3 kg m^-3 .
