<span>The better the RSM dissolves in the solvent, the higher the Rf (retention factor) will be, and the further the RSM will move.
If the RSM is a polar compound, increasing the polarity of the solvent will increase the Rf of the RSM. If the RSM isn't a polar compound, an increasingly polar solvent will decrease the Rf.</span>

Answer:125.0964g
Explanation:
Density = mass/volume
Density = 2.7 gcm-3
Volume=2.7*1.2*14.3=46.332
Mass=?
Mass= density* volume
= 2.7× 46.332=125.0964g
Uranus is said to be made of fluids. Its atmosphere is its surface
Answer:
250 mL (total solution) = 104 mL (stock solution) + 146 mL (water)
Explanation:
Data Given
M1 = 6.00 M
M2 = 2.5 M
V1 = 250 mL
V2 = ?
Solution:
As the chemist needs to prepare 250 mL of solution from 6.00 M ammonium hydroxide solution to prepare a 2.50 M aqueous solution of ammonium hydroxide.
Now
first he have to determine the amount of ammonium hydroxide solution that will be taken from6.00 M ammonium hydroxide solution
For this Purpose we use the following formula
M1V1=M2V2
Put values from given data in the formula
6 x V1 = 2.5 x 250
Rearrange the equation
V1 = 2.5 x 250 /6
V1 = 104 mL
So 104 mL is the volume of the solution which we have to take from the 6.00 M ammonium hydroxide solution to prepare 2.5 M aqueous solution of ammonium hydroxide
But we have to prepare 250 mL of the solution.
so the chemist will take 104 mL from 6.00 M ammonium hydroxide solution and have to add 146 mL water to make 250 mL of new solution.
in this question you have to tell about the amount of water that is 146 mL
250 mL (total solution) = 104 mL (stock solution) + 146 mL (water)
