Answer 1

Hey mate...here is ur ans.....✌❤❤

⏩1. No. of atoms = given mass / molar mass × avogadro no.

3.011 × 10^23 = x /14 × 6.022 × 10^23
x = 6.022 × 10^23 / 14 × 3.011 × 10^23
x = 14
✔mass = 14g

⏩2. No. of atoms = given mass/molar mass × avogadro no.

6.023 × 10^23 = x/28 × 6.022×10^23
x = 6.022×10^23 / 28 × 6.023×10^23
x = 28
✔mass = 28g

Hope it helps u....thanks...✌❤❤
