Question What is the molarity of a 400 mL solution containing 0.60 moles of NaCl?

Chemistry
1 answer:
Mumz [18]3 years ago
6 0

Answer:

0.24 M

Explanation:

Molarity = Moles solute / Liters solution

Step 1: Identify variables

400 mL = Liters solution

0.60 moles = Moles solute

Step 2: Identify conversions

1 L = 1000 mL

Step 3: Convert mL to L

400mL(1 L/1000mL) = 0.4 L

Step 4: Find molarity

M = (0.4 L)(0.60 mol) = 0.24 M

List the numbers of protons, neutrons, and electrons in Chlorine-18. (3 points)
Mama L [17]

The electronic configuration of Chlorine is 1s2 2s2 2p6 3s2 3p5.


There are three energy levels in chlorine


First energy level is n=1 has 1s2 so total 2 electrons


Second energy level is n=2, 2s2 2p6 so total 2+6= 8 electrons


Third has 3s2 3p5 electrons just 7 total... p can contain 6 electrons but only 5 are present. So the third level has lesser number of electrons than that can be filled

Which of the following statements best describes the current atomic theory
Oksana_A [137]
You did not provide the statements but a possible answer might be that the current atomic theory is sound and that technology that could challenge it does not exist at this time. There is no way to change it because no research can be done about it.

HELP HELP HELP ME PLSSSSS 50 POINTS
Anastaziya [24]

Answer:

1) They are the same line so they match equally bc they are measuring the same thing just one is more specific than the other

2) Sonar measures all depths at every possible point and maps it including all the gaps in between the 5cm apart the ocean floor is. The difference between the points could be a cliff or a smooth decline.

Calculate the number of kilojoules to warm 125 g of iron from 23.5 °C to 78.0 °C.
insens350 [35]
Given:
Iron, 125 grams T
1 = 23.5 degrees Celsius, T2 = 78 degrees Celsius.  

Required:
Heat produced in kilojoules  

Solution:
The molar mass of iron is 55.8 grams per mole. SO we need to change the given mass of iron into moles.  
 
Number of moles of iron = 125 g/(55.8 g/mol) = 2.24 moles  
<span>
Q (heat) = nRT = nR(T2 = T1)</span>
Q (heat) = 2.24 moles (8.314 Joules per mol degrees Celsius) (78.0 degrees Celsius – 23.5 degrees Celsius)
<u>Q (heat) = 1014.97 Joules or 1.015 kilojoules</u> <span>This is the amount of heat produced in warming 125 g f iron.</span>
