Answer:
Higher oxidation state metals form stronger bong with ligands
Explanation:
Ligand strength are based on oxidation number, group and its properties
The actual formula for volume for a cube is the length multiplied by the width and then multiplied by the height. Since all three measurements are the same, the formula results in the measurement of one side cubed. For the example, 5^3 is 125 cm^3. Multiply the volume by the known density, which is the mass per volume.
Answer:
0.21 M
Explanation:
The method to solve this question is to use Beer´s law which is expressed by
A = εcl
where A is the absorbance, ε is molar absorptivity ( M⁻¹·cm⁻¹ ), c is the concentration M (mol/L), and l is the path length in cm.
Solving for c in the above equation
c = A / εl = 0.458 / ( 2.16 M⁻¹·cm⁻¹ x 1.01 cm ) =0.21 M
Note: there is an error in the units for the absorptivity constant, it should have said M⁻¹·cm⁻¹ . You can check this by realizing the absorbance is unitless and when we multiply M⁻¹·cm⁻¹ with the units of concentration c (M) and path length (cm ) the units cancel.
