Answer:
0.65 M
Explanation:
Molarity (M) is the amount of moles of a substance per liter.
In other words, M = moles of substance / liters of solution
Since you're already given the moles of NaCl and the volume of the solution, you can plug those into the equation.
M = moles of NaCl / liters of solution
M = 1.5 mol NaCl / 2.3 L
M = 0.65 mol/L (or 0.65 M)
Answer:
Aluminum; [Ne]3s²3p¹
Arsenic; [Ar]3d¹⁰4s²4p³
Explanation:
<em>Aluminum</em>
From the periodic table, we have that aluminum, Al, is located in period 3, and group 3A of the periodic table
Therefore, the noble gas that comes before aluminum in the periodic table is neon Ne
The electronic configuration of aluminum is 1s²2s²2p⁶3s²3p¹
The electronic configuration of neon is 1s²2s²2p⁶
Therefore, the electronic configuration of aluminum in noble gas notation (Ne) is therefore;
[Ne]3s²3p¹
<em>Arsenic</em>
Arsenic is located after argon, Ar on the periodic table
The electronic configuration of arsenic is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p³
The electronic configuration of argon is 1s²2s²2p⁶3s²3p⁶
The electronic configuration of arsenic in noble gas notation (Ar) is given as follows;
[Ar]3d¹⁰4s²4p³
Answer : The speed in miles per hour is 22 mile/hr.
The speed in yard per min is 26617.8 yard/min
Explanation :
The conversion used for meters to miles is:
The conversion used for second to hour is:
The conversion used for meter per second to mile per hour is:
As we are given the speed of 407.0 meter per second. Now we have to determine the speed in miles per hour.
So, 
Therefore, the speed in miles per hour is 22 mile/hr.
The conversion used for meter to yard
1m = 1.09 yard
The conversion used for second to hour is:
The conversion used for meter per second to mile per hour is:
As we are given the speed of 407.0 meter per second. Now we have to determine the speed in yards per min
So, 
Therefore, the speed in yard per min is 26617.8 yard/min
