Aerosol:

Aerosol is a colloidal dispersion of liquid or solid in gas.

Thus a colloidal liquid suspended in a gas is called an aero sol is true

Aerosol is an example of colloidal dispersion and when a beam of light is fall on colloids then light is scattered means light is spread in all direction. It is a characteristic property of collides.

I think the correct answer is true. A colloidal liquid suspended in a gas is called an aerosol. It can be directly emitted into the atmosphere or they can be formed in the atmosphere by condensation. Hope this answers the question. Have a nice day.

If you have 16 g of manganese (II) nitrate tetrahydrate, how much water is required to prepare 0.16 M solution from this amount

Schach [20]

<u>Answer:</u> The amount of water required to prepare given amount of salt is 398.4 mL

<u>Explanation:</u>

To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Molarity of solution = 0.16 M

Given mass of manganese (II) nitrate tetrahydrate = 16 g

Molar mass of manganese (II) nitrate tetrahydrate = 251 g/mol

Putting values in above equation, we get:

$0.16M=\frac{16\times 1000}{251\times \text{Volume of solution}}\\\\\text{Volume of solution}=\frac{16\times 1000}{251\times 0.16}=398.4mL$

Volume of water = Volume of solution = 398.4 mL

Hence, the amount of water required to prepare given amount of salt is 398.4 mL
