When you want to melt an ice, you only need the latent energy of fusion, <span>δhfus. We use the given value, then multiply this with the given amount to determine the amount of energy. Since the energy is per mole basis, use the molar mass of ice which is 18 g/mol. The solution is as follows:
</span>ΔH = 5.96 kJ/mol * 1 mol/18 g * 500 g
<em>ΔH = 165.56 kJ</em><span>

Answer:
Volume of HBr = V₂ = 7.5 mL
Explanation:
Given data:
Volume of NaOH =V₁= 25.0 mL
Molarity of NaOH =M₁= 0.150 M
Molarity of HBr =M₂= 0.5 M
Volume of HBr =V₂= ?
Solution:
M₁V₁ = M₂V₂
0.150 M ×25.0 mL = 0.5 M×V₂
V₂ = 0.150 M ×25.0 mL / 0.5 M
V₂ = 3.75 M.mL /0.5 M
V₂ = 7.5 mL
