Answer:
54.2 g of Ca(OH)₂
Explanation:
Let's determine the moles of solute, we should need
Molarity . volume (L) = moles
Let's convert 600 mL to L
600 mL/ 1000 = 0.6L
1.22 mol/L . 0.6L = 0.732 moles
Finally we must convert the moles to mass ( moles . molar mass)
0.732 mol . 74.08 g/mol = 54.2 g
Answer: 54.2 g Ca(OH)2
Explanation: Molarity is moles of solute / L solution
First convert mL to L
600 mL x 1L / 1000 mL = 0.6 L
Find moles of Ca(OH)2
n= M x L
= 1.22 M x 0.6 L
= 0.732 moles Ca(OH)2
Convert moles to mass using its molar mass of Ca( OH)2 = 74 g
0.732 moles Ca(OH)2 X 74 g Ca(OH)2 / 1 mole Ca(OH)2
= 54.2 g Ca(OH)2
