Which phenomenon best explains the miscibility of heptane (CH3CH2CH2CH2CH2CH2CH3) in pentane (CH3CH2CH2CH2CH3)

1 answer:

6 0

The phenomenon that best explains the miscibility of heptane in pentane is that both are non-polar compounds.

<h3>Solubility of compounds</h3>

Solubility is defined as the ability of a solute or substance to dissolve in a given solvent and at a particular temperature.

Heptane is a straight-chain alkane hydrocarbon that contains 7 carbon atoms. It is a non polar solvent.

Pentane is also a straight-chain alkane hydrocarbon that contains 5 carbon atoms. It is also a non- polar solvent.

Both pentane and heptane are non-polar because the atoms in their molecules share electrons equally. They are able to dissolve each other because they are alike.

Monosodium glutamate (NaC5H8NO4) is used extensively as a flavor enhancer what is its percent composition

torisob [31]

Answer:

% sodium= 13.6 % sodium

% carbon= 35.5 % carbon

% hydrogen= 4.7% hydrogen

% nitrogen = 8.3% nitrogen

% oxygen = 37.8 % oxygen

Explanation:

To find its percent composition means that we are to find to find the percentage of each of the constituents of the compound present.

The molar mass of monosodium glutamate is 169.11 gmol-1

Hence;

Percent of sodium= 23 gmol-1/169.11 gmol-1 × 100 = 13.6 % sodium

Percent of Carbon= 60 gmol-1/169.11 gmol-1 ×100 = 35.5 % carbon

Percent of hydrogen= 8/169.11 gmol-1 ×100 = 4.7% hydrogen

Percent nitrogen = 14/169.11 gmol-1 × 100 = 8.3% nitrogen

Percent oxygen = 64/169.11 gmol-1 ×100 = 37.8 % oxygen

Calculate the volume in liters of a M potassium dichromate solution that contains of potassium dichromate . Round your answer to

maksim [4K]

The question is incomplete, here is the complete question:

Calculate the volume in liters of a 0.13 M potassium dichromate solution that contains 200. g of potassium dichromate . Round your answer to 2 significant digits.

<u>Answer:</u> The volume of solution is 5.2 L

<u>Explanation:</u>

To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (in L)}}$

We are given:

Molarity of solution = 0.13 M

Given mass of potassium dichromate = 200. g

Molar mass of potassium dichromate = 294.15 g/mol

Putting values in above equation, we get:

$0.13M=\frac{200}{294.15\times \text{Volume of solution}}\\\\\text{Volume of solution}=\frac{200}{294.15\times 0.13}=5.23L$

Hence, the volume of solution is 5.2 L
