Weight of one atom an element is `6.44 xx 10^(23) g`. Calculate g atom of elements in `40 kg`.

Explanation

To solve the problem, we need to calculate the gram atoms of an element in 40 kg, given that the weight of one atom of the element is \(6.44 \times 10^{-23}\) g.

### Step-by-Step Solution:

1. **Convert 40 kg to grams**:
\[ \text{Weight in grams} = 40 \, \text{kg} \times 1000 \, \text{g/kg} = 40000 \, \text{g} \]
