1,204x 10²² molekul C12H22O11=..... mol C12H22O11=...... g C12H22O11 tolong dijawab ya

Mol = jumlah molekul / bilangan Avogadro (Na)
Mol = 1.204 × 10^22 / (6.022 × 10^23)
Mol = 0.02 mol.

Ar C = 12, Ar H = 1, Ar O = 16
Mr C12H22O11 = (12 × 12 + 1 × 22 + 16 × 11)
Mr C12H22O11 = 342 g/mol

Massa = mol × Mr
Massa = 0.02 × 342 = 6.84 gram

Jumlah molekul = 1,204 x 10^22 molekul
L = 6,02 x 10^23
Mr C12H22O11
= 12xAr C + 22xAr H + 11xAr O
= 144 + 22 + 176
= 342


n C12H22O11
= jumlah molekul / L
= 1,204 x 10^22 / 6,02 x 10^23
= 0,2 x 10^-1
= 0,02 mol


Massa
= n x Mr
= 0,02 x 342
= 6,84 gram
