Answer: 0.0128 moles
Explanation:
Hg is the chemical symbol for the element, Mercury.
- The molar mass of mercury is 200.6.
- The reacting mass is 2.56g
Recall that the number of moles of any substance = Reacting mass ➗ Molar mass
So, Number of moles = 2.56/200.6
= 0.0128
Thus, there are 0.0128 moles of Mercury (Hg) in 2.56g of mercury
