9.00g/1hr * 1kg/100g * 1hr/60min = 0.00015kg/min or 1.5 * 10^-4kg/min.
Answer:
The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.
A unit cell is a simplest repeating unit in a crystal in which particle are freely vibrating
Sodium chloride having face centered cubic lattice in which sodium and chloride ion are arranged and vibrating.
The sodium ion are arranged on eight corners of the cube whereas they are also present on all the six centres of all six faces.
Thus, number of Na+ ion
Hence total of 14 sodium ions are present in NaCl lattice.
