3)<br>0.09 moles of sodium sulfate in 12 mL of solution.<br>​
adelina 88 [10]

Answer:

7.5 M

Explanation:

In order to find a solution's molar concentration, or molarity, you need to determine how many moles of solute, which in your case is sodium sulfate,  

Na

2

SO

4

, you get in one liter of solution.

That is how molarity was defined -- the number of moles of solute in one liter of solution.

So, you know that you have  

0.090

moles of solute in  

12 mL

of solution. Your goal here will be to scale up this solution by using this information as a conversion factor to help you determine the number of moles of solute present in

Why do mercury hardly evaporates in room temperature
Ratling [72]
All I can say is that Mercury is a liquid at room temperature, and liquids will very slowly evaporate at room temperature. This is because the molecules have a relatively low energy at room temperature (since room temperature is very low compared to boiling point). The boiling point of mercury is 356.73 degrees Celsius, and room temperature is only about 23 degrees Celsius, so the evaporation rate at room temperature would be little to nothing.

How many electrons in an atom can have each of the following quantum number or sublevel designations?
storchak [24]

10 electrons in an atom can have each of the 3d quantum number or sublevel designations.

<h3>What are four quantum numbers?</h3>

Quantum numbers are used to characterize the values of conserved quantities in a quantum system's dynamics in both quantum physics and chemistry.

1) The "n" sign refers to the principal quantum number. It shows how many shells there are.

2) The "l" sign indicates the azimuthal quantum number. It gives the form of the orbitals and their angular momentum. 0 to n-1 make up its range.

3) "m_{l}" stands for the magnetic quantum number. It serves as a cue for spatial orientation. The range of it is -l to +l.

4) Spin quantum number, represented by the symbol "m_{s}". It shows how the electron is spinning.
