The bond formed between two or more electrons of different atoms is called a COVALENT BOND.
        
                    
             
        
        
        
Answer:
Because Rutherford's model was weak on the position of the electrons, Bohr focused on them. He hypothesized that electrons can move around the nucleus only at fixed distances from the nucleus based on the amount of energy they have. ... However, an electron could never exist in between two energy levels

Hey there:
a) atomic mass:
Carbon =<span>12.0107 g/mol
</span>Hydrogen = <span>1.00794 g/mol
Oxygen =  </span><span>15.9994 g/mol
</span>
Therefore:
C12H22O11 = 
12 * 12.0107 + 1 * 1.00794 + 16 * 15.9994 => <span>342.29648 g/mol
__________________________________________________________
b) number of moles:
n = m / mm
n = 3.115 / </span><span>342.29648 
n = 0.0091 moles

hope this helps!</span>
