To solve this problem, we use Beer's Law: A= ε.l.c
A is the absorbance- 0,558
<span>ε is</span> the molar absorptivity- is <span>15000 </span><span><span>L⋅mol-1</span><span>cm-1</span></span>
<span>l is </span>the length of the cuvette- 1 cm
<span>c is</span> the molar concentration
Applying the formula,
0,558= 15000 x 1 x c
0,558/15000= c
c= <span>3.72×<span>10⁻⁵ </span> <span>mol⋅L<span>⁻¹</span></span></span>

D human dna which is a molecule in cell
Answer:
0.2335320064 mi/min
Explanation:
1 km/h = 0.0103561865 mi/min
1 mi/min = 96.56064 km/h
For conversion:
22.55 km/hr = 22.55 x 0.0103561865 mi/min = 0.2335320064 mi/min
The fertilizer they're putting down on the fields, will eventually run into waterways and contaminate the water and make the PH levels out of wack and cause the water to be polluted, it will also cause coral bleaching
