Calculate the mass of 6.022 × 1023 N2 molecules.

1.	Calculate the mass of 6.022 × 1023 N2 molecules.
Answer» We know, 1 mole = 6.022 × 10²³ Now, to calculate mass, apply the formula: Number of moles(n) = \(\frac{Mass(m)}{Molar\,mass(M)}\) we can write: Mass(m) = Number of moles (n) × Molar mass of N₂ (M) Mass = 1 mol × 28g/mol Mass = 28g Thus, the mass of 6.022 × 10²³ atoms of nitrogen is 28g

Answer»

We know, 1 mole = 6.022 × 10²³

Now, to calculate mass, apply the formula:

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

we can write:

Mass(m) = Number of moles (n) × Molar mass of N₂ (M)

Mass = 1 mol × 28g/mol Mass = 28g

Thus, the mass of 6.022 × 10²³ atoms of nitrogen is 28g
