Answer:

14 ml of water

Explanation:

To find the volume you need to dilute the concentration of a solution, you should use the formula C1 x V1 = C2 x V2 in which:

C1 = initial concentration ( in this case 60 %)

V1 = initial volume ( in this case 70 ml)

C2 = Final concentration ( you want to dilute until 50 %)

V2 = final volume ( the variable you want to search)

So you need to:

1.- Isolate the variable you want to find: V2 = (C1 x V1) / C2

2.- Substitute data: V2 = (60% x 70 ml) /50 %

3.- You do the math, in this case is 84 ml.

4.- Remember that you have a initial volume of 70 ml, so the difference (84 ml - 70 ml = 14 ml) is the volume you need to add to dilute your solution.

sp2 hybrid orbitals have 1. trigonal bipyramidal symmetry. 2. linear symmetry. 3. tetrahedral symmetry. 4. trigonal planar symme
Cloud [144]

Answer:

4. trigonal planar symmetry.

Explanation:

The sp2 hybridization is formed with one s and two p atomic orbitals and form  trigonal planar symmetry. In sp2 hybridization, there are same valence shell in both the orbitals and it gives three equivalent sp2 hybridized orbitals that are separated by 120 degrees giving trigonal planar symmetry.

Hence, the correct answer is "4. trigonal planar symmetry.".

How many grams of calcium chloride are dissolved in 5.65 liters of a 0.11 m solution of calcium choride?
Julli [10]
C = 0.11 mol
V = 5.65 L
n = ???

n = C*V
n = 0.11 * 5.65
n = 0.622 mols

1 mol of CaCl2 = 40 + 2*35.5 = 111 grams
0.622 mol = x

x = 111 * 0.622
x = 69.0 grams CaCl2
