Answer:
Explanation:
so u can work out the amount of moles of S8 by using
moles=mass/mr
=16/32.1=0.498moles
then use the molar ratio of
S : Fe
1:1 so the moles of Fe is the same 0.498
The use the equation
mass = mr x moles
=55.8 x 0.498
=27.78
so 27.8 g
hope this make sense :)
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant.
Answer:
Lewis structures, also known as Lewis dot diagrams, Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures, are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. A Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds
