Question

II) 6.022x10 23 number of N2 molecules ( mass from number​

Answer 1

Answer:

28g

Explanation:

First, we apply the formula:

⇒ Mass of N2 = No. of moles × Molar mass of N2

⇒ Mass of N2 = 1 mole × 2(atomic mass of nitrogen)

⇒ Mass of N2 = 1mole × 28u

⇒ Mass of N2 = 28g

Thus, mass of 6.022 × 1023 number of N2 molecules is 28g.
