Calculate the mass of 0.5 mole of N atoms.

1.	Calculate the mass of 0.5 mole of N atoms.
Answer» Given: Number of moles = 0.5 Atomic mass of N = 14 u Molar mass of N = 14g/mol To calculate the mass, apply the formula: Number of moles (n) = \(\frac{Molar\,(m)}{Molar\,mass\,(M)}\) we can write: Mass(m) = Number of moles (n) × Molar mass (M) Mass = 0.5 mol × 14g/mol Mass = 7g Thus, the mass of 0.5 mole of N atoms is 7g.

Answer»

Given:

Number of moles = 0.5

Atomic mass of N = 14 u

Molar mass of N = 14g/mol

To calculate the mass, apply the formula:

Number of moles (n) = \(\frac{Molar\,(m)}{Molar\,mass\,(M)}\)

we can write:

Mass(m) = Number of moles (n) × Molar mass (M)

Mass = 0.5 mol × 14g/mol

Mass = 7g

Thus, the mass of 0.5 mole of N atoms is 7g.
