Answer:
5.706x10⁻³M
Explanation:
Based on product solubility of Ca(OH)₂:
Ca(OH)₂(s) ⇆ Ca²⁺ + 2OH⁻(aq)
Ksp = 5.5x10⁻⁶ = [Ca²⁺] [OH⁻]²
<em>Where </em>[Ca²⁺] is 0.05M and [OH⁻] is obtained from the reaction with HCl.
The molar solubility, S, will be:
S = [OH⁻]/2
The [OH-] is:
<em>Moles HCl = Moles OH⁻</em>
2.77x10⁻³L * (0.103mol / L) = 2.85x10⁻⁴ moles OH⁻ in 25mL = 0.025L:
2.85x10⁻⁴ moles OH⁻ / 0.025L = 0.0114M = [OH⁻]
And S is:
0.0114M/2 =

Answer:
.✓is related to the solute content
✓gives information about potential changes in cell volume when cells are placed in that solution
√is related to membrane permeability to solutes.
Explanation:
Tonicity of a solution can be explained as how an extracellular solution can give room for the liquid to move in and out of the cell through osmosis.
It should be noted that Tonicity of a solution is
.✓is related to the solute content
✓gives information about potential
changes in cell volume when cells are placed in that solution
√is related to membrane permeability to solutes.
Answer: Since the mass (27) is equal to number of protons + number of neutrons, then number of neutrons = 27 - 13 = 14. 3.
