Question

11. Determine the number of molecules present in 0.25 mol of N204

Answer 1

The number of molecules : N = 1.505 x 10²³

Further explanation

Given

0.25 mol N₂O₄

Required

The number of molecules

Solution

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

N = 0.25 x 6.02.10²³

N = 1.505 x 10²³
