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:




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 Natoms is 7g.
