How many moles of water, H2O, contain 2.0×1022 molecules of water

Chemistry
1 answer:
andreev551 [17]3 years ago
6 0

Answer:

<h3>The answer is 0.03 moles</h3>

Explanation:

To find the number of moles given the 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

N = 2 × 10²² molecules of water

We have

n =  \frac{2 \times  {10}^{22} }{6.02 \times  {10}^{23} }  \\  = 0.033222591...

We have the final answer as

<h3>0.03 moles</h3>

Hope this helps you

The depictions of ionic compounds do not show distinct compound units but rather a collection of ions in the ratio given by the
Sedaia [141]

Answer:

The ionic compound NaCl has a Face Centered Cubic unit cell

The site for atoms are Face, center and Edges corner.

Effective number of atoms

Na+

1centers + 12edges x\frac{1}{4} = 4 Na+  

Cl-

6face x\frac{1}{2}  + \frac{1}{8} x8 corners = 4Cl-

This is just one unit cell effective atom, there are thousand's of such unit cells are combined to form one such structure of NaCl. The real formula of NaCl is Na4Cl4 but for simplicity we use empirical formula that is NaCl.

How many moles of carbon tetrachloride are produced when 4.63 mol of carbon reacts with
Ksivusya [100]

Answer:

4.63 moles of  CCl4

Explanation:

C + 2Cl2 = CCl4

The balanced equation tells us that we'll obtain 1 mole of CCl4 for every 1 mole of C, assuming we have 2 or more moles of Cl2 (which we do in this problem).

Therefore, if we start with 4.63 moles of C, we'll produce 4.63 moles of  CCl4
