Answer:
2.52moles
Explanation:
The amount of substance, measured in miles, can be calculated using the formula:
Number of moles = mass ÷ molar mass
According to the information in this question; mass of Mercury (Hg) = 505g, molar mass (MM) of Hg = 200.59g/mol
Hence, using mole = mass/MM
mole = 505/200.59
mole = 2.5175
mole = 2.52moles
