Answer:
46 g
Explanation:
First we <u>convert 1.2 x 10²⁴ atoms of sodium into moles</u>, using <em>Avogadro's number</em>:
- 1.2x10²⁴ atoms ÷ 6.023x10²³ atoms/mol = 2.0 mol
Then we <u>convert 2.0 moles of sodium into grams</u>, using <em>sodium's molar mass</em>:
- 2.0 mol Na * 23 g/mol = 46 g
Thus, there are 46 grams in 1.2x10²⁴ atoms of sodium.
I’m just letting you know this is really easy you just calculate the molar mass of each compound and divide the amount of the compound (grams) by the molecular Mass
Answer to question 5 is whatever expertnent you did in class.
