How many moles of nitrogen are in 3.7 moles of C8H11NO2?

3.7 Moles of Nitrogen

Explanation:

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.

Calculate Number of Moles of Nitrogen:

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
