how many hydrogen atoms are there in a formula unit of ammonium chloride?

One ammonium is surrounded by 4 hydrogen. Therefore the count of hydrogen is 8. If this was a question from a quiz, with a trap, one of the hydrogen is a proton (the one on the lone pair of nitrogen), therefore strictly speaking they are 6 hydrogen atoms.

Atomic mass of Bacl2 is 128 approx. So, number of cl atoms = 66.66% × 0.0167 × 6.023×10^10 atoms. i.e 6.73 × 10^21 cl atoms.

Due to the presence of symmetry elements, Ni(NH3)2Cl2 does not exhibit isomerism. The Geometry of Hexaamminenickel chloride is square planar. The reason for this is that the nickel is giving away four electrons and has no extra electron pairs floating around. Option (c) is the answer.

Essentially, atoms are the basic unit of an element (C, H, etc.) Molecules can contain multiple atoms bonded together. Formula units are a special term used for salts such as NaCl. Within the formula unit of NaCl, there are two atoms (Na and Cl).

A mole is a unit of measurement, which equals 6.02 * 10^23. If you have a mole of cl2, then you have 6.02 * 10^23 molecules of cl2. If you want to calculate for atoms however, you can see that each molecule has two atoms of cl. Therefore you have 2* 6.02 * 10^23 chlorine atoms.

Hydrogen chloride is a diatomic molecule, consisting of a hydrogen atom H and a chlorine atom Cl connected by a polar covalent bond. The chlorine atom is much more electronegative than the hydrogen atom, which makes this bond polar.

Ammonia, formed of 3 hydrogen atoms and a nitrogen atom, has an atomic weight of 17g/mol. (Actually 17.031g/mol if we're being picky.) This means that 17g of ammonia is one mole of ammonia. The number of molecules in a single mole of any compound is given by Avoadro's constant, which is 6.023x10^23.
