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.
The first solution or a I think is the correct answer
Hello!
Order of magnitude of a measure is an estimate of the base power 10 closest to a given measure.
The scientific notation (N) of 0.000000000333 (x), being (number of decimal places) y, knowing that the scientific notation according to the rule of scientific notation, before the comma can only have the numbers 1 to 9, let's see:
![N = x*10^y](https://tex.z-dn.net/?f=%20N%20%3D%20x%2A10%5Ey%20)
![N = 0.000000000333*10^y](https://tex.z-dn.net/?f=%20N%20%3D%200.000000000333%2A10%5Ey%20)
![\boxed{\boxed{N = 3.33*10^{-10}}}\end{array}}\qquad\checkmark](https://tex.z-dn.net/?f=%20%5Cboxed%7B%5Cboxed%7BN%20%3D%203.33%2A10%5E%7B-10%7D%7D%7D%5Cend%7Barray%7D%7D%5Cqquad%5Ccheckmark%20)
note: Moved 10 decimal places to the right negatively
I Hope this helps, greetings ... DexteR! =)
