Question

can anyone tell me how to calculate molar mass

Answer 1

Hola User_____________________

Here is Your Answer...!!!!
______________________________

⭐Actually welcome to the concept of the MOLE CONCEPT...

⭐Basically Molar mass can be calculated by ....

⭐1) In terms of moles ....

⭐Molar Mass = Given mass ÷ No . of moles ..

also .....

⭐When atomic mass or the Molecular mass Represent in terms of the grams is denoted as the Molar mass of the given element or the compound ....

⭐Example ...

⭐Calcium has atomic mass = 40 amu

⭐there fore its molar mass is 40 grams/mol ....

⭐Compounds like ...

⭐NaCl has atomic mass = 40 amu. ..
thus it's molar mass = 40 grams/mol

Answer 2

Molar mass can be calculated by just calculating the mass of all the atomes present in the molecule.

For example, water (H2O)

Molar mass of water = 2x (mass of hydrogen) + mass of oxygen.

=> 2 x 1 + 16
=> 18 g

Example 2.
The molar mass of methane (CH4)
=> mass of carbon atom + 4 x (mass of hydrogen)

=>12 + 4x1
=> 16 g
