In chemistry, the molar mass, M, is a physical property. It is defined as the mass of a given substance (chemical element or chemical compound) divided by its amount of substance.
The molar mass of atoms of an element is given by the atomic weight of the element multiplied by the molar mass constant, M
u = 1×10−3 kg/mol = 1 g/mol:M(H) = 1.007 97(7) × 1 g/mol = 1.007 97(7) g/molM(S) = 32.065(5) × 1 g/mol = 32.065(5) g/molM(Cl) = 35.453(2) × 1 g/mol = 35.453(2) g/molM(Fe) = 55.845(2) × 1 g/mol = 55.845(2) g/mol.
Multiplying by the molar mass constant ensures that the calculation is dimensionally correct: atomic weights are dimensionless quantities(i.e., pure numbers) whereas molar masses have units (in this case, grams/mole).

What is Hcl ???? If you mean HCl then the moleculart mass/weight is
H = 1
Cl = 35.5
HCl = 1 + 35.5 = 36.5
NB When writing chemical formula, single letter elemental symbols are ALWAYS a CAPITAL letter ; hydrogen as 'H' ,as given
However, Two letter elemental symbols are Always written ; first letter is a CAPITAL letter and the second letter is always 'lower' case' ; Hence Chlorine 'cl' shoukld be 'Cl'.
This is the recognised international standard, and as found in the Periodic Table.

The formula of zinc fluoride is ZnF2. Therefore, its molar mass is the sum of the atomic mass of zinc and twice the atomic mass of fluorine: 65.39 + 2(18.999) = 103.39; the last digit is depressed because it may not be significant, since the atomic mass of zinc (at least in my reference) has only four significant digits.

To obtain one mole of copper atoms (6.02 x 1023 atoms), weigh out 63.55 g copper. The molar mass (M) of a substance is the mass of one mole of entities (atoms, molecules, or formula units) of the substance. Molar mass has units of grams per mole (g/mol).
For More Detail
63.546 grams of Copper in 1 mole of Copper
(63.546g/mol) * (1mole/6.022*10^23) = 1.055*19^-22
Another way (But for the Copper 35 iostope):
1 atom of copper has 29 protons and 35 neutrons
29 protons * 1.00728 amu/proton = 29.21112 amu
35 neutrons * 1.00867 amu/neutron = 35.30345 amu
29.21112 + 35.30345 = 64.51457 amu total
(64.51457 amu) * (1 gram/6.02*10^23 amu) = 1.07167*10^-22 grams in one copper-35 atom

The molecular structure for 2,2-dimethylbutane is C6H14.
How to get: 2,2-dimethylbutane
- first to help you write the molecular formula you need to write the structural formula
- 2,2- tells you to put both methyl groups on the second carbon atom in the structural formula
- the prefix di- tells you that there are two methyl groups
- the prefix but- tells you that the longest chain of carbon atoms is four
- the suffix -ane tells you that there are only single bonds throughout the compound
After getting your structual formula wrote down, count up all the carbon atoms. You should get six. Then count all your hydrogen atoms. You should get fourteen.
