Answer:
0.68850323527 moles or 0.6885 moles
Explanation:
Molecular weight of compound (given): 25.50 g
First, find the molar mass for each element and add to get the molar mass of the compound.
N = 14.0067 g/mol
H = 4 * 1.00784 = 4.03136 g/mol
F = 18.998403 g/mol
Molar mass of the compound
14.0067 g/mol + 4.03136 g/mol+ 18.998403 g/mol = 37.036863 g/mol
Divide the given molecular weight of the compound to itthe computed molar mass to get the moles.
