Number of moles in 1.806*10^22 molecules of nitrogen
Fynjy0 [20]
Hi there!

• Avogadro's number = 6.023 × 10²³
• No.of molecules in N = 1.806 × 10²²  [ Given ]

It's known that :-

Number of molecules = Moles × Avogadro's number

=> 1.806 × 10²² = Mol. × 6.023 × 10²³

=> Mole = \dfrac {1.806 \cdot 10^{22} }{6.023 \cdot 10^{23} }

=> Moles = 0.03 mol.

Hence, 0.03 mol. is th' required answer.

earnstyle [38]

Answer: Krypton

Explanation:

7(14)=84

Krypton, if you look at the periodic table, has an atomic mass of approximately 84. It has a large nucleus, so while it is stable (due to its full octet) the nucleus is probably unstable due to repulsive forces between protons in the nucleus so is probably radioactive.
