Molar mass AgNO3 = <span>169.87 g/mol
1 mole AgNO3 ------------ 169.87 g
?? moles AgNO3 --------- 25.4 g
25.4 x 1 / 169.89 => 0.1495 moles</span>
The order of increasing polarity of the solvents is; hexane< diethyl ether < acetone < n-propanol < methanol < water
<h3>What is chromatography?</h3>
Chromatography literarily means "color writing". It provides a means of separating the components of a mixture based on its components.
The solvent in chromatography is the mobile phase while the adsorbent is the stationary phase. The order of increasing polarity of the solvents is; hexane< diethyl ether < acetone < n-propanol < methanol < water
If we have a mixture of n-propanol and water, it would be good to add hexane to the mixture for the sake of the elution of non-polar solutes.
The secondary color green may be composed of more than one color while red, blue and yellow are single colors.

Answer:
The cell membrane is located on the outside of a cell. It acts as a border that separates the cell from other cells or substances in the environment.
Explanation:
The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
<span>I'm assuming its cause the total mass is the same, changes between phases are physical... solid ice and liquid water have the same mass</span>
