what are the viscosities of vegetable oil, air, water, copper sulphate - CuSO4, salt and sugar?
I need the viscosity for each individual material at 25 degrees celcius please.
The copper sulphate, salt and sugar were dissolved in water to make a 0.5 Molar concentration for each.
80 g of CuSO4
29.25 g of Salt
161.1 g of Sugar
all mixed with 455 cm cubed water.

The viscosity of water at 25°C is
η = 8.91×10-4 Pa·s
The viscosity of air at 25°C is
η = 1.74×10-5 Pa·s
The viscosity of vegetable oil. cant be specified generally. Vegetable oil is a mixture fatty acids. There are several different types of vegetable of different composition. And of course the viscosity changes with compostiion.
Even for a particular oil like olive oil or palm oil the the compositions varies of a smaller range due to growing conditions, way of processing the vegetables, etc.
So just two examples i know:
olive oil
η ≈ 1×10-2 Pa·s
palm oil
η ≈ 3×10-3 Pa·s
Copper sulfate, salt and sugar are crystalline solids at 25°C. Crystalline solids don't have a viscosity because they don't flow.
