Question

How many mol of nitrogen is in 0.30 mol of caffeine

Answer 1

Moles of Nitrogen in 0.30 moles of caffeine is 1.2

Step-by-step explanation:

The molecular formula of caffeine is C8N4O2H10.

Based on the formula stoichiometry:

1 mole of caffeine contains-

8 moles of Carbon (C)

4 moles of nitrogen (N)

2 moles of oxygen (O)

10 moles of hydrogen (H)

Therefore, # moles of Nitrogen (N) in 0.30 moles of caffeine would be:

`= (0.30\ mole\ caffeine * 4\ moles\ N)/(1\ mole\ caffeine) = 1.2\ moles`

Answer 2

The moles of nitrogen in 0.30 mole of caffeine is calculated as follows

write the chemical formula = C8H10N4O2

for this case from the chemical formula we have 4 atoms of nitrogen in caffeine

therefore moles of nitrogen in caffeine = 4 x0.30 =1.2 moles
