Why one mole of different compounds have different masses but have same number of molecules?
One mole of different compounds have different masses but have same number of molecules because that is the definition of a mole - a mole is about 6.022x1023 molecules of any particular material - and is normalized to the mass of Carbon-12.
What do the nuclei of different plutonium isotopes have in common?
The nuclei of different plutonium isotopes all contain 94 protons, which define the element as plutonium. The isotopes differ in the number of neutrons they contain, resulting in different atomic masses for each isotope.
What are atoms of the same element but with different masses?
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
John Dalton gathered evidence for the existence of atoms by measuring the masses of elements that reached to form compounds True or False?
True. John Dalton proposed his atomic theory based on experiments where he measured the masses of elements that combined to form compounds, leading him to conclude that all matter is composed of indivisible atoms.
Is lithium batteries an element mixture or compound?
Any battery must contain at least two distinct chemical substances, and there is no fixed ratio between the masses of the two substances. Therefore, any battery, including a lithium battery, is a mixture.
Why does 10 g nitrogen gas contain the same number of molecules as 10 g of carbon monoxide?
These compounds have equal molar masses.
Why one mole of different compounds have different masses but have same number of molecules?
One mole of different compounds have different masses but have same number of molecules because that is the definition of a mole - a mole is about 6.022x1023 molecules of any particular material - and is normalized to the mass of Carbon-12.
Why don't equal masses of carbon and oxygen contain the same number of atoms?
The atoms are different sizes.
Does a galaxy contain an average of 100 billion solar masses?
Yes. A galaxy does contain an average of 100 billion solar masses.
Why dont equal masses of golf balls and ping pong balls contain the same number of balls?
Their densities are different.
Why different objects have different masses?
Objects have different mass because they not weighted the same..
What do the nuclei of different plutonium isotopes have in common?
The nuclei of different plutonium isotopes all contain 94 protons, which define the element as plutonium. The isotopes differ in the number of neutrons they contain, resulting in different atomic masses for each isotope.
10 kinds of isotopes and their application?
Different atoms of the same element possessing different atomic masses but having same atomic number are known as Isotopes. Since the isotopic atoms have the same atomic number, they must contain an equal number of protons. As their atomic masses are different, there must be a difference in the number of neutrons they possess. They will show similar chemical properties but their physical properties will be different due to different masses.
Lymph nodes contain dense masses of?
Lymphocytes
How is it possible for objects to have the same volume but different masses?
Their masses are different. (Mass = density * volume)
What is the name for atoms of an element that have different masses?
An atom or element that have different masses are known as isotopes.
Is it possible for atoms of the same chemical element to have different masses?
Yes, different isotopes of the same element have different masses.
