Question

How to convert molecular weight from gram per mole to lbs per mole?

Answer 1

Hint : The pound is the unit of money which is used in the UK. The short form of the unit is lbs. One UK pound is divided into a hundred pence. So, we have to convert the unit for molecular weight from grams per mole to lbs per mole. Both pounds and grams are units of length and can be changed into one another. So, we can do so by using the unitary method.

Complete Step By Step Answer:
In the given question, we are required to convert molecular weight from grams per mole to lbs (or pounds) per mole. We can do so with the use of the unitary method. In the unitary method, we first find the value of one unit and then subsequently multiply the value of one unit by the desired number.
So, we know that $1$ kilogram $= 2.205$ lbs (pounds).
So, we can find the value of $1$ gram in pounds as we know that $1$ kilogram $= 1000$ grams.
Hence, we get, $1000$ grams $= 2.205$ lbs (pounds).
Hence, $1$ gram $= \dfrac{{2.205}}{{1000}}$ lbs (pounds).
$\Rightarrow 1$ gram $= 0.002205$ lbs (pounds).
So, we get one gram per mole as $0.002205$ lbs or pounds per mole.
Therefore, the molecular weight can be converted from gram per mole to lbs per mole by using the above conversion and multiplying the weight by $0.002205$ .

Note :
In the given question, we need to convert grams into pounds or lbs. The required task can be done by following the unitary method in which we find the value of one unit and then multiply the equation by the desired number. Care should be taken while converting units of weight and while carrying out subsequent calculations.
