From the <span>ideal gas law,
n = PV / RT
n= moles = W / M
W= weight
M = molar mass
So, W / M = PV /RT
=> M = WRT / PV
We got above the formula for molar mass.
Now, put the appropriate values.
W= 0.8 g
R=0.0821 atm / K-mol
T= 373 K
V= 256mL = 0.256 L
P = 750 torr = 750 / 760 = 0.987 atm
After putting these values and calculating the value of M, we get :
M = 97 g / mol
Now, </span>Assuming the molecular formula is

So, molar mass = n × <span>(12.01 + 1.01 + <span>35.45)
equate it with 97.
We get the value of n then:
</span></span>n×<span>(12.01 + 1.01 + 35.45) = 97
n = 2
Means molecular formula is </span>

Answer:
The compound is a saturated fatty acid.
Explanation:
Fatty acids are <u>carboxylic acids with a long chain</u>, which can be 3-carbon long-chain atoms or above. According to the saturation of its bonds, they can be saturated (all single bonds) or unsaturated (mono or polyunsaturated, depending on the number of double bonds present in the molecule).
In this case, since it is a saturated fatty acid and it has 26 carbons, it is called cerotic acid, or hexacosanoic acid.
There is really no difference thermal energy and heat are pretty the same thing.
it is formed when the element chlorine gains an electron or when a compound such as hydrogen chloride is dissolved in water
