Question

How to convert molecular weight from g/mol to lb/nom?

Answer 1

Hint: The answer is dependent on the conversion using the required parameters whether lb means nothing but the pound – mole and thus the conversion of g/mol into pounds will give the required answer.

Complete answer:
The concept of the basic part of the chemistry which deals with the conversions of several quantities from one form to another and also the significant figures and other parameters are known to us.
Let us see the concept of conversion of molecular weight of the compound from g/mol to lb/mol.
- Molecular weight is defined as the mass of a molecule that is based on the atomic mass of the carbon -12 atom and is calculated by summing the atomic weights of the atoms making up the molecular formula of the substance.
- The unit for the molecular mass or molecular weight is basically in terms of g/mol of a substance.
- ‘lb’ is the notation of American origin which means pounds – mole and also the value will be, 1kg = 2.2 lb
Therefore, we know that 1kg is equal to 1000g
Thus, 1g of the substance will be
\[1g=\dfrac{2.2}{1000}\approx 0.0022lb/mol\]
Therefore, the above value can be written as,
\[1g\approx 2.2\times {{10}^{-3}}lb/mol\]
Therefore, the correct answer is 1 g/mol will be equal to\[2.2\times {{10}^{-3}}lb/mol\]

Note:
Note that ‘lb’ can also be written in the plural form of pound – unit mass as ‘lbs’ and the actual abbreviation of ‘lb’ is from the Latin word ‘Libra’ which means pound and the full expression is called as ‘Libra pondo’ which means ‘pound weight’.
