How can you determine the atomic mass of an unknown metal if you know its density and the dimension of its unit cell? Explain.

How can you determine the resolving power of your eye?

Establish the expression for density of a unit cell from the dimension of its unit cell.

How can you determine co-efficient of friciton by inclined plane method?

How can you find the mass of earth, starting from the law of gravitation?

Estimate the average mass density of a sodium atom assuming its size to be about 2.5 A- (Use the known values of Avogadro’s number and the atomic mass of sodium). Compare it with the density of sodium in its crystalline phase: 970 kg m^(-3) . Are the two densities of the same order of magnitude? If so, why

An element X with atomic mass 60U has density 6.23gcm^-3 . If the edge length of its cubic unit cell is 400pm, identify the type of cubic unit cell calculate the radius of an atoms of this element.
