Hitunglah nilai mol pada: a.56 gram N2 b.1,204 x 1024 atom fe

a. mol= gram/Mr
    mol= 56/28
    mol= 2 mol

b. mol Fe= 1,024 x 10^24/6,02x10^23
    mol Fe= 2 mol

Kimia XI

(A)
Mr N₂ = 2(14) = 28

mol = massa/Mr
mol = 56 / 28
mol N₂ = 2 mol

(B)
mol = jumlah atom / 6,02 x 10²³
mol = 1,204 x 10²⁴ / 6,02 x 10²³
mol Fe = 2 mol
