Concentration is the number of moles of solute in a fixed volume of solution
Concentration(c) = number of moles of solute(n) / volume of solution (v)
25.0 mL of water is added to 125 mL of a 0.150 M LiOH solution and solution becomes more diluted.
original solution molarity - 0.150 M
number of moles of LiOH in 1 L - 0.150 mol
number of LiOH moles in 0.125 L - 0.150 mol/ L x 0.125 L = 0.01875 mol
when 25.0 mL is added the number of moles of LiOH will remain constant but volume of the solution increases
new volume - 125 mL + 25 mL = 150 mL
therefore new molarity is
c = 0.01875 mol / 0.150 L = 0.125 M
answer is 0.125 M
Answer:
yes
Explanation:
because they are all the same revolving round the sun the colors only differ
Answer:
The partial pressure of BrCl at equilibrium is 0.08 atm.
Explanation:
The equilibrium constant of the reaction is given by =
initial
0 0 0.500 atm
At equilbrium
p p (0.500-2p)
The equilibrium constant's expression of the reaction is given by ;
![K_p=\frac{[BrCl]^2}{[Br_2][Cl_2]}](https://tex.z-dn.net/?f=K_p%3D%5Cfrac%7B%5BBrCl%5D%5E2%7D%7B%5BBr_2%5D%5BCl_2%5D%7D)
Solving for p:
p = 0.21 atm
The partial pressure of BrCl at equilibrium is:
(0.500-2p) = (0.500 - 2 × 0.21 )atm = 0.08 atm[/tex]
Because of the heat, steam
