It is called a cycle because it is repetitive, therefore making it a cycle (or almost never ending)
Answer:
The correct answer is 0.6 mL.
Explanation:
We use the mathematical expression:
Ci x Vi = Cf x Vf
Where Ci is the initial concentration (5 M); Cf and Vf refers to final concentration (0.002 M) and final volume (1500 mL). With the given data, we calculate the initial volume (Vi):
Vi = (Cf x Vf)/Ci = (0.002 M x 1500 mL)/(5 M) = 0.6 mL
Therefore, we need 0.6 mL of 5 M NaCl to prepare the solution with the requested dilution.
<h3>Answer:</h3>
3.7 Moles of Nitrogen
<h3>
Explanation:</h3>
On observing the chemical formula C₈H₁₁NO₂ (might be formula of Dopamine) it is found that one mole of this compound contains;
8 Moles of Carbon
11 Moles of hydrogen
1 Mole of Nitrogen and
2 Moles of Oxygen respectively.
<u>Calculate Number of Moles of Nitrogen:</u>
As,
1 Mole of C₈H₁₁NO₂ contains = 1 Mole of Nitrogen
So,
3.7 Moles of C₈H₁₁NO₂ will contain = X Moles of Nitrogen
Solving for X,
X = (3.7 Moles × 1 Mole) ÷ 1 Mole
X = 3.7 Moles of Nitrogen
