The answer is rounded off to 0.0278 mol C6H12O6
The molecular geometry of a compound helps to determine polarity b/c, it indicates the number of lone pairs on a central atom thus giving it specified angles and polarity (only if there are lone pairs b/c if there are no lone pairs on the central atom, then it is nonpolar.
Answer:
As estrelas produzem a sua energia por um mecanismo chamado fusão nuclear. Nesse processo dois elementos simples se fundem para produzir um elemento mais pesado, liberando muita energia. ... Neste caso ocorre exatamente o contrário da fusão: Átomos muito pesados (como o Urânio) são quebrados, liberando energia.
The mass number of an isotope is determined by the number of neutrons in the isotope plus the number of protons.
For instance Carbon-13 is an isotope of carbon. The "13" is the mass number of the isotope.
So, in this example, 13 = #protons + #neutrons
Answer:
2.881x10^23 atoms
Explanation:
From the studies of Avogadro's hypothesis, we discovered that 1mole of any substance contains 6.02x10^23 atoms.
Therefore 1mole of Fe contains 6.02x10^23 atoms.
Molar Mass of Fe = 56g/mol
56g of Fe contains 6.02x10^23 atoms.
Therefore, 26.8g of Fe will contain = (26.8x6.02x10^23) / 56 = 2.881x10^23 atoms
