Question

Calculate the number of gram atoms in $4.6$grams of Sodium$\left(Na\right)$

Answer 1

Part one : Introduction to gram atom

• The atomic mass of an element is gram atom.
• This is also called as moles.

Part two: The calculation of gram atom

• One gram atom of Sodium$\left(Na\right)$ is equal to $23gSodium\left(Na\right)$
• $4.6$grams of Sodium$\left(Na\right)$ will contain

$$\begin{gathered} g-atom=\frac{4.6}{23} \\ g-atom=0.2 \end{gathered}$$

Therefore, the gram atoms in $4.6$$grams$ of Sodium$\left(Na\right)$ are $0.2g-atom$
