Question

existe 160 gr de sulfato cuprico disuelto en 100 ml de solución la molaridad de disolución es?

Answer 1

Mm CuSO4 = 159.60 g/mol

1. calcular moles

mol = masa / Mm

mol = 160 g / 159.60 g/mol

mol = 1.002

2. calcular M

V = 100 / 1000 = 0.1 L

M = mol soluto / V (L)

M = 1.002 mol / 0.1 L

M = 1.002 mol / 0.1 L

M = 10.02 molar
