Answer:
E. 6.9 E-7 M
Explanation:
0.10M 0.10M 0.10M
eq: S S 2S + 0.1
∴ Ksp = 6.9 E-9 = [Mg2+][F-]² = (S)(2S+0.1)²
if we compared the concentration ( 0.1 M ) with the Ksp ( 6.9 E-9 ); then we can neglect the solubility as adding:
⇒ Ksp = 6.9 E-9 = (S)(0.1)² = 0.01S
⇒ S = 6.9 E-9 / 0.01 = 6.9 E-7 M
Answer:
6.63 M
Explanation:
NaCl(s) ---> Na^+(aq) + Cl^-(aq)
Given that [Na^+] = [Cl^-] = s
Where s= concentration of the both ions
Ksp = s^2
s= √Ksp
s= √43.9
s= 6.63 M
