What is the formula of the percentage by mass and volume?
Percentage by Mass = Mass of substance of interest/Total Mass Percentage by Volume = Volume of substance of interest/Total Volume Converting from one to the other requires information about their relative densities.
What is the formula of the percentage by mass and volume with diffinition?
The percentages refer to the amount of a substance of interest that is contained in a compound or mixture of that and other substances. Percentage by mass = 100*mass of substance of interest/total mass. Percentage by volume = 100*volume of substance of interest/volume mass. And, incidentally, the word is definition, not diffinition.
Haemoglobin in percentage?
In percentage of what in what species, or objects. It is 0% in water! The percentage will depend on what the denominator is. there will be a huge difference between haemoglobin as a percentage of total blood or percentage of total body mass. Also it will vary: people living at high altitudes tend to have higher concentrations.
What is the mass percentage of 02?
It is zero. The number 02 is a number. It is a concept and no physical existence and no mass. So the mass percentage is zero.
How do you get a cumulative percentage having a mass percentage?
You cannot. The two are different things!
The human cerebral cortex accounts for what percentage of the total mass of the brain?
The human cerebral cortex accounts for about 80% of the total brain mass. It is responsible for higher brain functions such as thinking, memory, and voluntary movement.
Why is the human cerebellum is split in half while the sheep cerebellum is one mass?
The human cerebellum is split in half while the sheep cerebellum is one mass for a few reasons. This is because the human brain is more complex.
How many neurons does the cerebellum have?
How many neurons does the cerebellum have? This is an interesting question. Of the sources I have reviewed thus far, I have not found a consistent approximation of neurons in the cerebellum. The human brain has (estimate) 100 billion neurons. Some sources say 10-100 billion. According to Wikipedia, the cerebellum takes up 10% of the brain's total volume and contains roughly 50% of all the neurons in the brain. In that case, 50 billion neurons in the cerebellum. However, in the book I'm currently reading, it has suggested that the cerebellum neuron count is more like 70 billion. Therefore, the cerebrum (rest of the brain) has the remaining 30%. Interesting isn't it? Such a small structure contains majority of the brain's neurons. Additionally, the cerebellum has Purkinje cells, which are among the largest neurons in the brain. According to Wikipedia, Granule cells (very tiny neurons) are very numerous in the cerebellum which are accountable for the mass % of neurons in this particular cortex. Hope I have helped you! However, take note that to some people Wikipedia is not a valid source. To me it's reliable in some circumstances. The book I'm reading now was written by an M.D so I feel that is more reliable, so I'll go ahead and say that the cerebellum has (estimate) 60-70 billion neurons.
What is the formula of the percentage by mass and volume?
Percentage by Mass = Mass of substance of interest/Total Mass Percentage by Volume = Volume of substance of interest/Total Volume Converting from one to the other requires information about their relative densities.
What is the percentage composition of molar mass in the given compound?
The percentage composition of molar mass in a compound is the percentage of each element's mass contribution to the total molar mass of the compound.
HOW TO GET percent of magnesium by mass?
To calculate the percentage of magnesium by mass in a compound, divide the mass of magnesium by the total mass of the compound, then multiply by 100. Percentage of magnesium by mass = (mass of magnesium / total mass of compound) * 100.
Do the cerebral hemispheres account for about 83 percent of total brain mass?
No, the cerebral hemispheres account for about 85-90% of the total brain mass. They are the largest part of the brain and are responsible for higher brain functions such as memory, reasoning, and emotions.
Is the cerebellum the largest and most prominent region of the human brain that is responsible for the voluntary or conscious activities of the body?
No, the cerebellum is not the largest or most prominent region of the human brain. It is responsible for coordinating voluntary movements, balance, and posture, rather than conscious activities like decision-making. The cerebrum, which makes up the majority of the brain's mass, is responsible for higher cognitive functions.
HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE?
First, determine the mass of ethanol in the mixture by dividing the mass of ethanol by the total mass of the mixture. Then, multiply the result by 100 to get the percentage by mass of ethanol in the mixture. For example, if a mixture contains 20g of ethanol in a total mass of 100g, the percentage by mass of ethanol would be (20g / 100g) * 100 = 20%.
How does the total mass percentage of alkaline earth metal ions compare with the total mass percentage of alkaline metal ions?
The total mass percentage of alkaline earth metal ions is higher than that of alkaline metal ions in a compound since alkaline earth metals have a higher atomic mass compared to alkali metals. This means that alkaline earth metals contribute more to the total mass of the compound when present as ions.
Can the concentration of a liquid dissolved in a liquid can be expressed as a percentage by mass?
Yes, the concentration of a liquid dissolved in a liquid can be expressed as a percentage by mass. This is commonly calculated by dividing the mass of the solute by the total mass of the solution and then multiplying by 100 to get a percentage.
What is the percentage of a mixture homogeneous?
The percentage composition of a mixture has nothing to do with its homogeneity or otherwise. A mixture is homogeneous if its percentage composition - whatever that is - is the same throughout the mixture.
