Answer : The concentration of ion is, 0.00371 M
Explanation :
First we have to calculate the concentration of ion.
The solubility equilibrium reaction of will be:
The expression for solubility constant for this reaction will be,
Now we have to calculate the concentration of ion.
The solubility equilibrium reaction of will be:
The expression for solubility constant for this reaction will be,
Thus, the concentration of ion is, 0.00371 M
Answer:
I think is A 690 nm or c 500 nm

While waves that travel within the depths of the ocean are longitudinal waves
Explanation : the waves that travel along the surface of the oceans are referred to as surface waves. A surface wave is a wave in which particles of the medium undergo a circular motion. Surface waves are neither longitudinal nor transverse.
First you should find no of mole.
a mole is a measurement of the number of number of grams in which there are 6.02 x 10^23 atoms/molecules of a substance.
1.468 moles of NH3 in 25 grams.
(25/17.0306) 1.468 x (6.02 x 10^23) = 8.837 x 10^23 molecules.
hope this help
