Question

State True or False. Weight of a given substance = Number of moles $\times$ gram molecular weight of the substance.

• A. True
• B. False

Answer 1

The correct option is A True

This is the simple formula to calculate the weight of a substance when the number of moles are given.
For example:

Here, if we are to calculate the weight(in gm) of 0.7 moles of Sodium.
The gram molecular weight of Sodium is 23.
Therefore, the number of moles = 0.7 X 23 = 16.1
