He is using the filtration method.
It’s a technique which is used for separation of solids and fluids by putting them through a medium which allows only fluid to pass through, leaving the solids (in this case the soil) alone.
The fluid that passed is called the filtrate.
The pressure of a gas is the force that a gas exerts per unit area of the container.
Pressure is defined as force per unit area. Gas molecules are constantly colliding against the walls of the container. The pressure of the gas is the force the gas is exerting on its container.
Since temperature is defined as the average kinetic energy of the molecules of a gas then the higher the temperature, the faster the particles move.
The volume of a container refers the size if the container.
The pressure of a gas is inversely proportional to its volume according to Boyle's law. Thus implies that if the pressure of the gas goes up, the volume has to go down.
For a compound to be called an acid, it must contain H+ and H3O+ when dissolved in water.
For a compound to be called a base, the compound must dissolve in water to yield hydroxide ions.

Answer:
751.8kg/m3
Explanation:
Assuming water's density is 1,000 kg/m3 and acetone's density is 791kg/m3
we use the formula
![\frac{1}{p} = summatory \frac{xi}{pi}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7Bp%7D%20%20%3D%20summatory%20%5Cfrac%7Bxi%7D%7Bpi%7D%20)
where 1/p is the density of the mixture, xi is the mass fraction and pi is the individual density of the components of the mixture.
To calculate xi we consider that acetone and water are in a 50% proportion, this means xi is 0.5 for both substances, now we can substitute in the formula:
![\frac{1}{p} = \frac{0.5}{1000} + \frac{0.5}{791} = 0.00133](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7Bp%7D%20%20%3D%20%5Cfrac%7B0.5%7D%7B1000%7D%20%20%2B%20%20%5Cfrac%7B0.5%7D%7B791%7D%20%20%3D%200.00133)
now we obtain p.
<em>p=751.8kg/m3</em>
I hope you find this information useful! good luck!
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].
