Explanation:
Molarity is defined as the the number of moles present in a solution divided by volume in liters.
Mathematically, Molarity =
As it is given that number of moles present into the solution are 2.00 moles and volume is 4 liter. Therefore, calculate the molarity of solution as follows.
Molarity =
=
= 0.5 M
Thus, we can conclude that the concentration of given solution is 0.5 M.
The percent composition of Uranium in U308 = C. 81.03%
<h3>Further explanation</h3>Given
X g of U
3.795 g of O
20.00 g of U308
Required
The percent composition of Uranium
Solution
mass of Uranium in U308 :
= mass of U308 - mass of O
= 20 g - 3.795 g
= 16.205 g
The percent composition :
%U = (mass U/mass U308) x 100%
%U= (16.205/20) x 100%
%U = 81.025≈81.03

Explanation:
Hello,
In this case, since in a dilution process the moles of the solute must remain unchanged, we use the volumes and molarities as shown below:
Clearly, the concentrated solution is 7.00M and the diluted solution is unknown, thus, the concentration of the diluted solution after the dilution to 100 mL is:
