Molarity= moles/ liters
first you need to calculate the moles using the molar mass of the molecule to convert grams to moles
molar mass MgO= 40.3 grams/ mole
62.5 gram MgO (1 mole/ 40.3 grams)= 1.55 mole
Molarity= 1.55 mole/ 1.50 Liters= 1.03 M
The answer is 1.98 × 10^22 iron (II) ions
I think the answer is true
Answer:
I think it's B but I could be wrong so really sorry if I am
Answer:
Ksp FeS = 5.2441 E-18
Explanation:
S S S
∴ Ksp = [Fe2+]*[S2-].....solubility product constant
∴ [S2-] = 2.29 E-9 M = S
⇒ Ksp = (S)(S) = S²
⇒ Ksp = (2.29 E-9)²
⇒ Ksp = 5.2441 E-18
