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.

These compounds have equal molar masses.


Two molecules with the same number and type of atoms but have them in a different arrangement or order are called?

They are different molecules--They are, however, related by the law of multiple proportions. This law states that when different compounds are formed by a combination of the same elements, different masses of one element combine with the same relative mass of the other element in a ratio of small whole numbers.

180 g of glucose and 342 g of sucrose have same number of molecules but different number of atoms. Explain?

They are different compounds with different molecules:- the chemical formula of glucose is C6H12O6- the chemical formula of sucrose is C12H22O11


How many different types of compounds In total?

There are millions of different types of compounds, ranging from simple molecules like water (H2O) to complex organic compounds like proteins and DNA. The exact number of different types of compounds is difficult to pinpoint due to the vast number of possible combinations of elements.


Equal volumes of nitrogen and oxygen at the same temperature and pressure would?

If equal volumes of nitrogen and oxygen are at the same temperature and pressure, then both (the nitrogen and oxygen) will contain the same number of particles


What are binary molecular compounds made out of?

Everything you can touch is made up of molecules. From simple compounds like water (H2O) to giant molecules that make up biological tissue. Only the noble/Inert gases exist as monatomic atoms.


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.


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.


What atoms has different masses but the same atomic number?

Isotopes of an element have different masses but the same atomic number. Isotopes have the same number of protons and electrons but different numbers of neutrons in their nuclei.


What has different atomic masses?

Different atoms and elements that have different number of protns, neutrons and electrons.Duh!


What atoms with same atomic number but different atomic masses?

Isotopes are atoms with the same number of protons (same atomic number) but different numbers of neutrons, leading to different atomic masses. For example, carbon-12 and carbon-14 are isotopes of carbon with atomic number 6 but atomic masses of 12 and 14 respectively.


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.
