hitung jumlah mol dari a.25 gram NaCl

Massa molar
Na + Cl = 23 + 35.5 = 58.5 g/mol

Massa = 25g

Massa Molar = Massa ÷ Mol
58.5g/mol = 25g ÷ Mol
58.5Mol = 25
Mol = 0.427350... = 0.427mol

Semoga Membantu :]

Massa = 25 gram
Mr NaCl
= Ar Na + Ar Cl
= 23 + 35,5
= 58,5


n NaCl
= Massa / Mr
= 25 / 58,5
= 0,42 gram
