Explanation:

It is known that an atom consists of protons, neutrons and electrons. Both protons and neutrons are located inside the nucleus of an atom whereas electrons revolve around the nucleus.

Atomic number is the total number of protons present in an atom. On the other hand, atomic mass is the sum of total number of protons and neutrons present in an atom.

That is,     Atomic mass = no. of protons + no. of neutrons

                 no. of neutrons = atomic mass - no. of protons

Therefore, we can conclude that to find the number of neutrons in an atom, subtract its number of protons from atomic mass.

How many grams of mercury are needed to react completely with 157g of sulfur to form hgs?
Salsk061 [2.6K]
<span>To solve this we need to balance the equations first.
 So Hg + S --> HgS is balanced
 One mole of Hg requires one mole of S to form one mole of HgS.
 Number of moles of Sulphur = mass/ molar mass = 157/32 = 4.906
So 4.90 moles of S reacts with 4.90 moles of Hg.
Hence there are 4.90 moles of 4.90 of Hg.
 Mass = number of moles * molar mass of Hg
Mass = 4.906 * 200.59 = 982.891g</span>
