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.
How many different masses of the Cl2 molecule would you expect to find in a sample of chlorine gas?
three different masses.
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?
it is true
Do solids liquids and gases have different masses?
Yes they do.

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 don't equal masses of carbon and oxygen contain the same number of atoms?
The atoms are different sizes.
Why do 2 objects of different masses dropped from the same height hit the ground at the same time?
Most likely because they're the same weight. Objects can have completely different masses and have the same weight.
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.
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
Compounds join in a specific ratio according to their masses?
It is true for the simple compounds you are likely to meet in school chemistry. If the ratio is fixed we call it a stoichiometric compound. Sodium chloride is always NaCl and magnesium chloride is always MgCl2. Lead and oxygen can form PbO, PbO2 and Pb3O4 but each of these is a different substance and each always has a fixed elemental ratio. However there are many more complex compounds which have variable composition. A common example is rust.
How is it possible for objects to have the same volume but different masses?
Their masses are different. (Mass = density * volume)
Is it possible for atoms of the same chemical element to have different masses?
Yes, different isotopes of the same element have different masses.
How is masses classified?
Air masses are classified according to their maritime source regions and their latitude. Different air masses affect different parts of the world.
