Answer:
46 g
Explanation:
First we convert 1.2 x 10²⁴ atoms of sodium into moles, using Avogadro's number:
- 1.2x10²⁴ atoms ÷ 6.023x10²³ atoms/mol = 2.0 mol
Then we convert 2.0 moles of sodium into grams, using sodium's molar mass:
- 2.0 mol Na * 23 g/mol = 46 g
Thus, there are 46 grams in 1.2x10²⁴ atoms of sodium.
