Question

de o número de mol de: 400g de NaOH

Answer 1

Olá!!!

MM(NaOH) = 23 + 1 + 16 = 40g/mol

1 mol ---------- 40g
X --------------- 400g

X = 1 mol • 400g / 40g

X = 400 / 40

X = 10 mol

ou

n = m / MM

n = 400g / 40g/mol

n = 10 mol

Answer 2

Resposta:

MM(NaOH) = 23 + 1 + 16 = 40g/mol

1 mol ---------- 40g

X --------------- 400g

X = 1 mol • 400g / 40g

X = 400 / 40

X = 10 mol

ou

n = m / MM

n = 400g / 40g/mol

n = 10 mol
