8.2 grams = 1 mol
Na ________
22.99 grams
First multiply the value of 8.2 to 1. Then divide by the value of 22.99 to determine the number of moles of sodium present in the 8.2 gram sample.
Then use the following equation to solve for sodium atoms.
Number of moles of Na • Avogadro Number = Number of sodium atoms.
0.3566782 • (6.02 X 10^23). = 2.1472 X 10 ^ 23. Or 2.15 X 10 ^ 23.
The answer is the second option - 2.15 X 10 ^ 23.

I pressed "find" without changing any of the settings, and scrolled down until I saw what was in the attached screenshot.
Each of the rows correspond to the first, second, and third answers, as you can see.
I hope this helps!

Can you help me on my recent question?
Answer:
Step-by-step explanation:
Okay, I'm assuming you want us to figure out how much the hat costs.
To start off, let's figure out how much the gloves cost after the discount. 35 / 100= 0.3. We multiply that by 70%, since that is how much of the price is going to be left over after deducting 30%. We get $24.50.
So;
$44.80 of the total bill - $24.50=$20.30.
So we now know the hat cost $20.30.
