Respuesta :
Ans: 1.4 moles
Given:
Mass of tungsten = 250 g
To determine:
Moles of Tungsten
Explanation:
# moles of a given substance = Mass of the substance in grams/molar mass (g.mol-1)
Atomic mass of W = 184 g.mol-1
# moles of W = 250 g/184 g.mol-1 = 1.359 moles
The study of chemicals is called chemistry. There are two types of solution in the chemistry and these are acid and base.
The correct answer to the question is as follows:-
What are moles?
- The mole is the base unit of the amount of substance in the International System of Units.
- It is defined as exactly 6.02214076×10²³ elementary entities, which may be atoms, molecules, ions, or electrons.
The data is given as follows:-
- Mass of tungsten = 250 g
- Atomic mass of W = 184 g.mol-1
The formula used is as follows:-
moles of a given substance = Mass of the substance in grams/molar mass (g.mol-1)
Moles of W = [tex]\frac{250}{184}-1 = 1.359 moles[/tex]
Hence, the correct answer is 1.359.
