Calculate the gram atoms in 46 g of sodium [Na = 23]

Gram atoms is the relative atomic mass of an element expressed in grams.

$\text{Gram atoms} = \dfrac{\text{Mass in grams [of sodium]}}{\text{Rel. atomic mass [At. wt.]}} \\[0.5em] = \dfrac{46}{23} = 2 \text { gram atoms}$

Hence, gram-atoms in 46 g of sodium is 2 g. atoms
