Yes some mixtures can be separated lets say sand and water the sand is insoluble therefore you can separate it using filtration so it really depends on the mixture but yes they can be

Yes mixtures can be separated....by using some methods like fractional distillation,sublimation,filteration etc
As mixtures are of two types homogeneous and heterogeneous it depends upon the mixtures that how they'll be separated like if u take a mixture of iron granules and sugar then u will use magnet for mixture of water and sugar u will use evaporation method if sugar and salt is mixed then put the solution in alcohol then one of them either sugar or salt will be eliminated

820 mol of hydrogen gas hydrogen gas has a volume of 2.00 l at a certain temperature and pressure. what is the volume of 0.125 m

Tcecarenko [31]

To solve this problem, let us first assume that the hydrogen gas acts like an ideal gas. So that we can make use of the ideal gas equation:

P V = n R T

where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant and T is the absolute temperature

Since it is given that T and P is constant therefore we can write the equation as:

V / n = k

So equating the two conditions:

V1 / n1 = V2 / n2

We can now solve for the new V2 given n2 = 0.125:

2 L / 820 mol = V2 / 0.125 mol
