Carbon. All organic molecules are hydrocarbons (contain hydrogen and carbon)
Answer:
<h2>Density = 0.67 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
To calculate the Density in g/mL we must first convert the mass from kg to g and the volume from L to mL
<u>For the mass</u>
That's
1.34 kg
1kg = 1000 g
1.34 kg = 1000 × 1.34 = 1340 g
<u>For the volume</u>
That's
2.0 L
1 L = 1000 mL
2.0 L = 2 × 1000 = 2000 mL
So we have
mass = 1340 g
volume = 2000 mL
Substitute the values into the above formula and solve for the Density
That's
<h3>
</h3>
We have the final answer as
<h3>Density = 0.67 g/mL</h3>

The sentence "The molality is independent from the
temperature whereas molarity is dependent on temperature" is false.
Molarity is also independent of temperature. When solving for the molarity, it
does not require any temperature because molarity is just the moles of solute
divided by liters of solvent.
Answer:
These are two types of indicators which show a solution is either an acid a natural or an alkali solution

Triglyceride is a molecule constituted by one one molecule of glycerol and 3 molecules of fatty acids. The structure of a glycerol is like a letter "E", where the vertical line ( | ) is the glycerol and the three horizontal lines are long chains of organic acids, each with one COOH group, called fatty acids.<span> The answer is that the other 3 molecules that make up a triglyceride are fatty acids.</span>
