What is the volume, in milliliters, of 6.52 g of acetone?
Answers
The mass of acetone is 6.52 g and its density is 0.791 g/mL.
The density of a substance is defined as its mass per unit volume. It is mathematically written as:
Rearranging above equation,
Putting the values,
Therefore, volume of acetone will be 8.24 mL.

Explanation:
First, figure out what 10^5 is. It is 100000. Then multiply it by 4 and there is your answer!
Also if it is 4x10^-5, it is 0.00004!
Oh yeah! If you want it to be in scientific notation, it is: 4x10^5
Since that I didn't quite understand what you are trying to question, it is either 4x10^5 or 4x10^-5!

The substrate, enzyme pair from the citric acid cycle that is INCORRECT is E) Citrate, aconitase.
The citric acid cycle, also known as the Krebs cycle, is a crucial metabolic pathway for generating energy in cells. Each step involves specific substrates and enzymes. While all other options (A, B, C, and D) correctly match substrates and enzymes involved in the cycle, option E (Citrate, aconitase) is incorrect.
Aconitase is responsible for catalyzing the interconversion of citrate and isocitrate, not for the conversion of citrate itself. The correct pair for citrate is citrate synthase, which catalyzes the formation of citrate from oxaloacetate and acetyl-CoA.
Understanding these substrate-enzyme pairs is essential in comprehending the citric acid cycle's intricacies. Accurate knowledge of these reactions aids in grasping how cells produce energy through this pathway. This emphasizes the significance of precise knowledge of biochemical pathways for an accurate understanding of cellular processes.
In the context of cellular metabolism, identifying the correct enzyme for each substrate is vital for accurate biochemical analysis and the design of targeted interventions for metabolic disorders. Among the given options, the substrate, enzyme pair that is incorrect in the citric acid cycle is Citrate, aconitase.

Final answer:
The incorrect substrate-enzyme pair from the citric acid cycle is Oxaloacetate, citrate synthase.
Explanation:
The citric acid cycle, also known as the Krebs cycle or tricarboxylic acid cycle, is a series of chemical reactions that occur in the mitochondria of cells. It plays a crucial role in the aerobic respiration process, generating energy-rich molecules such as ATP.
The citric acid cycle involves the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. Each step of the cycle is catalyzed by a specific enzyme, which acts on a particular substrate.
The correct substrate-enzyme pairs in the citric acid cycle are as follows:
- Isocitrate, isocitrate dehydrogenase
- Succinyl CoA, succinate dehydrogenase
- Fumarate, fumarase
- Oxaloacetate, citrate synthase
- Citrate, aconitase
Therefore, the incorrect substrate-enzyme pair from the given options is D) Oxaloacetate, citrate synthase.

b. The mass of the nucleus of the atom
c. The mass of the neutrons in the atom
d. The mass of the electrons in the atom
Answers
Both the protons and the neutrons are inside the nucleus. The atomic number of an atom is the number of protons, and if you subtract the atomic number from the atomic mass you can find the number of neutrons an atom has.
So, the mass of the protons plus the mass of the neutrons, which are both inside the nucleus, equals the atomic mass.
