Answer:
Solubility may be stated in various units of concentration such as molarity, molality, mole fraction, mole ratio, mass (solute) per volume (solvent) and other units. The extent of solubility ranges widely, from infinitely soluble (without limit) ( miscible) such as ethanol in water, to poorly soluble, such as silver chloride in water.
Explanation:
The mass of water equals the mass of the hydrate minus the mass of the anhydrite 4.9 G -2.9 G equals 2.0 G of water moles of water equals the mass of water/the molar mass of water 2.0 GH20/18 G/MOLHTO equals 0.11 Moles H20
Answer: -
Zero
Explanation: -
Double bond equivalent or level of unsaturation is the number of unsaturation present in a organic molecule. The term unsaturation may refer to a double bond or a ring system.
The double bond equivalent for an organic compound can be found out by the help of the formula
DBE = C+1 -0.5 H - 0.5 X + 0.5 N
The chemical formula of the compound B = C₇H₁₆O
So there are 7 carbons, 16 hydrogens and 1 oxygen. There is no halogen or nitrogen.
Plugging into the formula,
DBE = 7 + 1 - 0.5 x 16
= 0
Thus there is no unsaturation or double bond present in the compound B with the molecular formula C₇H₁₆O
Explanation:
Given :
Amount of solute - sucrose (C12H22O11) = 41 g
Amount of solvent -soda = 355-mL
Molarity of the solution with respect to sucrose= ?
Molarity(M) is a unit of concentration measuring the number of moles of a solute per liter of solution. The SI unit of molarity is mol/L.
Formula to find the molarity of solution :
Molarity =
Amount of solvent is given in mL, let’s convert to L :
1 L = 1000 mL
Therefore, 355 mL in L will be :
= 0.355 L
We have the amount of solute in g, let’s calculate the number of moles first :
Number of moles (n) =
Molar mass of C12H22O11 = 342.29 g/mol.
Therefore, n =
= 0.119 moles.
