We need to separate different components of a mixture to separate the useful components from the non-useful or some harmful components.
Examples:
(a) Tea leaves are separated from tea.
(b) Pebbles are separated form rice and pulse.
Molarity is number of moles of solute per one liter of solution. The symbol for molarity is a capital M. The molarity of the given solution will be 3.125M
A solution is a mixture of two or more substances in which neither of substance changes chemically. For example, the salt water is a solution that contains the water (the solvent) and salt (the solute). Concentration is amount of dissolved substance in a solution. In other words, it is amount of stuff that has been mixed into the liquid. Concentration is usually measured in the molarity.
Given that,
Number of moles= 1
Volume = 320ml= 0.320 L
Molarity= No of moles of solute/ Volume of solution in L
= 1/ 0.320
= 3.125 M

Answer:
58.94 mL
Explanation:
V1 = 48.3 mL V2 = v mL
T1 = 22 degree celsius OR 295 k T2 = 87 degree celsius OR 360 k
We will use the gas equation:
PV = nRT
Since the Pressure (p) , number of moles (n) and the universal gas constant(R) are all constants in this given scenario,
we can say that
V / T = k , (where k is a constant)
Since this is the first case,
V1 / T1 = k --------------------(1)
For case 2:
Since we have the same constants, the equation will be the same
V / T = k (where k is the same constant from before)
V2 / T2 = k (Since this is the second case) ------------------(2)
From (1) and (2):
V1 / T1 = V2 / T2
Now, replacing the variables with the given values
48.3 / 295 = v / 360
v = 48.3*360 / 295
v = 58.94 mL
Therefore, the final volume of the gas is 58.94 mL
Answer:
The height of the waves vary. The wave height is much larger for the air boat than for the mosquito.
