Calculate the percentage of N is ammonia molecule.

Ammonia molecule is:

Assuming oxygen molecule to be spherical in shape, calculate the volume of a single molecule of oxygen if its radius is 150 pm. Also calculate the percentage of empty space in one mole of the gas at STP.

The internuclear distance of H-F molecule is 0.92 Å and dipole moment is 2 debye . Calculate the percentage of ionic character of the molecule .

Draw the structure of ammonia molecule.

The molecular mass of ammonia is 17. a) How much is the GMM of ammonia? b) Find out the number of moles of molecules present in 170g of ammonia. c) Calculae the number of ammonia molecules present in the above sample of ammonia?

0.36 g of a nitrogeneous organic compound was Kejldahilised and the ammonia liberated was exactly neutralised by 20 ml of 0.3 N H_(2)SO_(4_ . Calculate the percentage of nitrogen in the compound.
