- By x-ray diffraction it is possible to determine the geometric pattern in which atoms are arranged in a crystal and the distances between atoms. In a crystal of silver, four atoms effectively occupy the volume of a cube 0.409 nm on an edge. Taking the density of silver to be 10.5 g/cm3, calculate the number of atoms in one mole of silver.arrow_forwardComplete the following table for TNT (trinitrotoluene), C7H5(NO2)3.arrow_forwardThe compound 1-propanethiol, which is the eye irritant released when fresh onions are chopped up, has the chemical formula C3HyS and a formula mass of 76.18 amu.
