c is the answer a benzene
Answer:
Compounds are pure substance consisting of two or more different atoms
The neutralization equation is:
3 Ca(OH)₂ + 2 H₃PO₄ → Ca₃(PO₄)₂ + 6 H₂O
From this equation we can see that 3 moles of Ca(OH)₂ react with 2 moles of H₃PO₄
Numbers of mmol of Ca(OH)₂ = M x V = 0.04345 x 54.93 = 2.387 mmol
Number of mmol of H₃PO₄ = 2.387 x (2/3) = 1.591 mmol
Molarity of solution = n (mmol) / V(ml) = 1.591 / 25 = 0.0636 M
