I’m guessing you mean moles. So the big M stands for mol/L. That means first you’d want to convert your mL to L. To do this write your 250mL then make parenthesis for the conversion. 1L=1000mL
250mL(1L/1000mL). Since the mL is on the bottom in the parenthesis we can cancel them out. Now all we do is divide and keep the L.
.250L is what you get. Now we need to figure out how to cancel the L with what we have left. We know M stands for Moles/L so this means in order to get ride of L we need to multiply our new number times the 1.5
.250L X 1.5 moles
_______
1L
This gives us 0.375 moles NH4SO4
Only a few ions (in comparison to others that totally break apart)
0 1 2 3
0 and 3 is 3
1 and 2 is 3
The formula that shows the correct representation of the combined gas law is; V1P1 / T1=V2P2 / T2
The combined gas law is obtained from the statements of Charles law and Boyle's law as follows;
Charles law; V/T = k
Boyle's law = PV = k
Combining the two I have; PV/T = k
For two masses of an ideal gas;
V1P1 / T1=V2P2 / T2
This is the statement of the combined gas law.

Answer:
Paper chromatography is a method used to distinguish or separate coloured substance mixtures.
In the image, take an example of colured chemical placed in a glass beaker. If a paper is placed in that chemical, coloured spots are separated and displayed on the chromatogram.
It was founded in 1944 A.D by a scientist called Erwin Cargaff.
