The structure that corresponds to methylpropylether is the structure CH3 - O - C3H7 in option C.
<h3>What is structure?</h3>
The structure of a compound is defined as the way in which the atoms in the compound are arranged. We know that a compound is composed of atoms and these atoms are arranged in particular patterns in space. This is the stereochemistry of the molecule.
Now we know that methylpropylether is a compound that contains the methyl group and the propyl group separated by a oxygen atom as is typical of all ethers.
As such, the structure that corresponds to methylpropylether is the structure CH3 - O - C3H7 in option C.

Answer:
3.7 ×10⁴ m
Explanation:
We know that,
1 miles = 1609.34 meter
We need to find how many meters are there in 23.1 miles.
23 miles = 37175.85 m
or
23 miles = 3.7 ×10⁴ m
So, there are 3.7 ×10⁴ m in 23.1 miles.
As we know, NaOH is a strong Base and completely dissociates in water as given below,
NaOH + H₂O → Na⁺ ₍aq₎ + OH⁻ ₍aq₎
So, the concentration of OH⁻ Ions will be the same as that the concentration of NaOH i.e. 0.018 M.
So,
[OH⁻] = 0.018 M
The moles of NaOH used in the titration would be 0.00177 moles while the molarity of the vinegar will be 0.885 M
<h3>Titration calculation</h3>
Recall that: mole = molarity x volume
In this case, the molarity of the NaOH= 0.1 M
Volume of NaOH = 17.7 - 0.0 = 17.7 mL
Mole of NaOH used = 0.1 x 17.7/1000 = 0.00177 moles.
Since NaOH and vinegar have 1:1 mole ratio, the mole of vinegar will also be 0.00177 moles.
Molarity of vinegar = mole/volume = 0.00177/0.002 = 0.885 M

<u>Answer:</u> The mass of a solute is 35 grams
<u>Explanation:</u>
To calculate the mass percentage of solute, we use the equation:
Mass percent of solute = 10 %
Mass of solution = 350 g
Putting values in above equation, we get:
Hence, the mass of a solute is 35 grams
