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

This poll is unbiased because only the students in the poll are saying that basketball is better. You should have a poll that includes everyone. That should give everyone a opportunity on saying what’s better and will get you a biased answer
Answer:
y=2 16/25
in other words, two and sixteen twenty-fifths
Step-by-step explanation:
y/2-1/5=2-y/3
Move the variables to one side and constants to the other
y/2+y/3=2+1/5
Multiply y/2 by 3/3 and y/3 by 2/2 so that they have a common denominator
3y/6+2y/6=2 1/5
5y/6=11/5
Cross multiply
66=25y
y=66/25
y=2 16/25

Answer:There are four students working on a project in math class. Miguel has completed 1/8 of the project, Gina has completed 13% of the project, Jatziry has completed 0.10 of the project, and Keva has completed 1/9 of the project. Make a list of the students in order from least to greatest by the amount of the project they have completed.
