The molar mass of lif is 25.94 g/mol. how many moles of lif are present in 10.37 g?
2 answers:
Answer : The number of moles of LiF are, 0.399 mole
Explanation : Given,
Mass of LiF = 10.37 g
Molar mass of LiF = 25.94 g/mole
Now we have to calculate the moles of LiF.
Now put all the given values in this formula, we get the number of moles of LiF.
Therefore, the number of moles of LiF are, 0.399 mole

Answer:
Number of Hydrogen Bond Acceptor atoms = 2
Number of Hydrogen Bond Donor atoms = 1
Explanation:
Hydrogen bond interactions are formed between those molecules which contains partial positive hydrogen atoms bonded covalently to most electronegative atoms like Oxygen, Nitrogen and Fluorine.
When hydrogen is attached to Oxygen, Nitrogen or Fluorine its electron density decreases and gets partial positive charge, this partial positive charged hydrogen atom then makes hydrogen bonding with the most electronegative element (partial negative) of neighbor molecule.
In Acetic acid there are two oxygen atoms hence there are two most electronegative elements therefore, two Hydrogen Bond Acceptor atom and each oxygen atom can accept two hydrogen bonds.
Also, it contains only one Hydrogen atom attached to oxygen atom so it has one Hydrogen Bond Donor atom.
Number of Hydrogen Bond Acceptor atoms = 2
Number of Hydrogen Bond Donor atoms = 1
