Answer:
The answer to your question is 35.03 g
Step-by-step explanation:
Data
mass of nitrogen = ?
moles of nitrogen = 2.5
Process
1.- Look for the atomic mass of nitrogen (look for in the periodic table)
Atomic mass = 14.01 g
2.- Use proportions to solve this problem. remember that the atomic mass is equal to one mol.
14.01 g of Nitrogen ------------- 1 mol
x ------------- 2.5 moles
x = (2.5 x 14.01) / 1
x = 35.03 g of Nitrogen
