What is the amount of molecules in 5 moles of nitrogen gas, N2?

The amount of molecules= 3.01 x 10²⁴

Given

5 moles of N2

Required

The number of molecules

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

For 5 moles :

= 5 x 6.02 x 10²³

= 3.01 x 10²⁴

the answers would be

the first one and the second one
