Answer:
HBr(aq) + LiOH(aq) → LiBr(aq) + H2O(l)
Explanation:
A neutralization reaction is a process in which an acid, aqeous HBr reacts completely with an appropriate amount of base, aqueous LiOH to produce salt, aqueous LiBr and water, liquid H2O only.
HBr(aq) + LiOH(aq) → LiBr(aq) + H2O(l)
Acid + base → Salt + Water.
During this reaction, the hydrogen ion, H+, from the HBr is neutralized by the hydroxide ion, OH-, from the LiOH to form the water molecule, H2O.
Thus, it is called a neutralization reaction.
Answer:
mm = 1043.33 g/mol
Explanation:
osmotic pressure (π):
∴ π = 17.8 torr = 0.0234 atm
∴ Cb: solute concentration
∴ T = 25°C = 298 K
∴ R = 0.082 atm.L/K.mol
⇒ Cb = π/RT
⇒ Cb = (0.0234 atm)/((0.082 atm.L/K.mol)(298 K))
⇒ Cb = 9.585 E-4 mol/L
molar mass (mm):
⇒ mm = (1.00 g/L)(L/9.585 E-4 mol)
⇒ mm = 1043.33 g/mol
Answer:
The molarity of the solution is 0.29 
Explanation:
Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.
Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:

Molarity is expressed in units
.
In this case:
- number of moles of solute= 2.1 moles
- volume= 7.3 liters
Replacing:

Molarity= 0.29 
<u><em>The molarity of the solution is 0.29 </em></u>
