Answer:
4084.808 grams (SigFigs: 4085 grams)
Explanation:
The molar mass of Iron fluoride is 112.84 g/mol.
To calculate the mass, multiply the molar mass by the number of moles.
36.2 mol * 112.84 g/mol = 4084.808 g
Convert to Sigfigs (if necessary):
4085 g
Answer:
36.8 g/mol of O
Explanation:
To find the number of grams, multiply the number of moles by the atomic mass of the element.
Oxygen has an atomic mass of 16.00.
2.3 moles O × (16.00 g O ÷ 1 mole) = 36.8 g/mol O
Hope that helps.
Answer : Nuclear fusion plays an important role in making elements that are heavier than helium.
Explanation : In the given attachment it is clearly observed that nuclear fusion reactions are playing a vital role in making the small elements fuse together to form a higher element as a product. This is observed in those elements which are heavier than helium. The atoms of the elements fuse together and make a larger atomic molecule which is the sum of both the elemental masses.
