Answer:
Moles of mercury (I) nitride are 0.014 mol.
Step-by-step explanation:
Given data:
Number of moles of mercury (I) nitride = ?
Mass of mercury (I) nitride = 17.5 g
Solution:
Molar mass of mercury (I) nitride:
(Hg₂)₃N₂ = (2×200.59)×3 + 14.0067 × 2
(Hg₂)₃N₂ = 1203.54 + 28.0134
(Hg₂)₃N₂ = 1231.5534 g/mol
Formula:
Number moles = mass / molar mass
Number of moles = 17.5 g / 1231.5534 g /mol
Number of moles = 0.014 mol
