Molecules from `10mL` of `1mM` surfactant solution are adsorbed on `0.24cm^(2)` area forming unimolecular layer. Assuming surfactant molecules to be cube in shape, determine the edge length of the cube.
10 ml of 1 millimolar surfactant solution forms a monolayer covering 0.24cm^(2) on a polar substrate. If the polar head is approximated as a cube. Consider the surfactant is adsorbed only on one face of the cube. What is the edge length of cube? (Answer should be in pm and assume Avogadro's number =6xx10^(23) ).
If the length of the edge of a cube is 3.2 cm, then the total surface area of the cube is
If a metalic cube of edge 1 cm is drawn into a wire of diameter 3.5 mm, then find the length of the wire.
Three metallic solid cubes of sides 6 cm, 8 cm and 10 cm are melted to form a single cube. The length of the edge of the new cube is
A container contains 1 litre, 2 M solution of cyclobutane in either. A piece of 3 kg charcoal is dipped in the solution. Molecules of cyclobutane get adsorbed on the surface of charcoal and form monolyer cyclobutane. The molarity of resulting solution decreases to 1 M. If surface area availble for adsorption on charcoal 2 cm^(2)//gm . Then find distance (in pm) between two adjacent carbon atoms in a cyclobutane molecule. (Assume: Shape of cyclobutane molecules as a perfect square.) [Use : N_(A) = 6xx10^(23) ]
From the solid gold in the form of a cube of side length 1 cm, spherical solid balls each having the surface area pi^(1//3) cm^(2) are to be made. Assuming that there is no loss of the material in the process of making the balls, the maximum number of balls made will be
