Question

150.0 g of AsF3 was reacted with 180.0 g of CCl4 to produce AsCl3 and CCl2F2. The theoretical yield of CCl2F2 produced, in moles, is?

a]0.7802 mol
b]1.274 mol
c]1.170 mol
d]0.5685 mol
e]1.705 mol

Answer 1

the general equation is
2AsF3 + 3CCl4 -----------> 2AsCl3 + 3CCl2F2
2mol 3mol
n mol ------------------------------------------------> ?
n (AsF3) =m/M= 1.13mol

so, n/2 = x/3 implies x = 3n/2 = 3*1.13 / 2= 1.69 mol it is near 1.7
the answer is e]1.705 mol
