Answer:
251 g of compound contain 2.39 moles.
Explanation:
Given data:
mass of compound Al(CN)3 = 251 g
moles = ?
Solution:
First of all we will calculate the molar mass of given compound.
molar mass of Al(CN)3 = 26.98 + (26 × 3)
molar mass of Al(CN)3 = 105 g/mol
Formula:
number of moles = mass/ molar mass
number of moles = 251 g / 105 g/mol
number of moles = 2.39 mole
