Properties of matter

    I am told solid manganese exists in a simple cubic structure. If its Ar is 54.94 and its density is 7440 Kg m^-3, How do I calculate the lattice constant for this material?

    Hi adambinch, welcome to PF. You need to find out how many atoms there are in the simple cubic unit cell. Then you can set up a calculation like


    and the volume per unit cell should lead you to the lattice parameter. Does this help?
