Question

cuantas moles hay en 100 g de HNO3

Answer 1

Mm HNO3 = 63 g/mol

Mol = masa / Mm

mol = 100 g / 63 g/mol

mol = 1.587 de HNO3

Answer 2

moles = gramos / MM

MM HNO₃ = (1 g/mol×1) + (14 g/mol×1) + (16 g/mol×3)
                 = 1 g/mol +14 g/mol + 48 g/mol
                 = 63 g/mol

mol = 100 g
          63 g/mol

mol = 1,59 mol
