A sample of substance x that has a mass of 326.0 g releases 4325.8 cal when it freezes at its freezing point. if substance x has
zysi [14]

The molar heat of fusion for substance X , given the data is 775.6 cal/mol

<h3>How to determine the mole of the substance X</h3>
  • Mass = 326 g
  • Molar mass = 58.45 g/mol
  • Mole = ?

Mole = mass / molar mass

Mole = (326 / 58.45) moles

<h3>How to determine the heat of fussion</h3>
  • Mole (n) = (326 / 58.45) moles
  • Heat (Q) = 4325.8 cal
  • Heat of fusion (ΔHf) = ?

Q = n × ΔHf

4325.8 = (326 / 58.45) × ΔHf

4325.8 = (326 × ΔHf ) / 58.45

Cross multiply

326 × ΔHf = 4325.8 × 58.45

Divide both sides by 326

ΔHf = (4325.8 × 58.45) / 326

ΔHf = 775.6 cal/mol

grigory [225]

Answer:

$48

Step-by-step explanation:

You can figure out how much he charges per single bag by diving the price by the amount of bags in the ratio, so 10 divided by 5 which equals two. So $2 per bag and 24 bags, multiply that and you find that it's $48.
