Ответ:
The answer is:![3.63x10^{24}particles](/tpl/images/0407/5572/12a39.png)
Why?First, we need to calculate the molecular weight of the acetone (CH3COCH3)
So,
Then,
Second, we need to calculate the mass of the acetone in the bottle
We need to remember that![1cm^{3}=1mL](/tpl/images/0407/5572/d0d04.png)
So,
Third, we need to calculate the number of moles:
Fourth, we need to calculate the number of atoms:
Remember,![1 mol=6.022x10^{23}particles](/tpl/images/0407/5572/fa5b7.png)
Therefore,
Have a nice day!
