CALCULATE THE MOLES IN 2.17 X10^23 MOLECULES OF FLUORINE

Chemistry
1 answer:
Cerrena [4.2K]3 years ago
4 0

Answer:

<h2>0.36 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{2.17 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{2.17}{6.02}  \\  = 0.360465...

We have the final answer as

<h3>0.36 moles</h3>

Hope this helps you

You are balancing an ionic compound. Let's call it: AB.
rewona [7]

Answer:- A_3B_2

Explanations:- It is given that the charge for A is +2 and the charge for B is -3. The over all compound is neutral means the over all charge is zero. For making the over all charge zero, we need 3 positive ions and 2 negative ions. This makes a +6 charge for A and -6 charge for B and the over all charge is zero.

Also, if we think about the criss cross then charge of A becomes the subscript of B and the charge of B becomes the subscript of A.

So, the formula of the ionic compound is A_3B_2 . In this compound the ratio of A to B is 3:2.

The balanced equation could be shown as:

3A+2B\rightarrow A_3B_2
