an iron supplement is used to treat anaemia and 50mg of iron 2 is required per tablet.if the iron compound used in the tablet is FeSO4.7H2O,what mass of this compound would be required per tablet to provide the desired amount of iron 2?
I know that the edge for the first one is 2r so in terms of r the lattice point (pt) would = 16. To find the face diagonal using the Pythagorean theorem it would be (2r)^2+(2r)^2= (face diagonal)^2.. But every time I would plug it in, its incorrect. And for the body diagonal, ...
