Answer:
13701.66 g
Step-by-step explanation:
Moles is denoted by given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
From the question ,
114.0 g-moles of cumene means ,
Moles of cumene = 114.0 g-mol
The Chemical formula of cumene = C₉H₁₂
As we know the molecular mass of cumene = 120.19 g /mol
using the above formula ,
n = w / m
w = n * m
Putting the corresponding values -
w = (114.0 g-mol) * 120.19 g /mol
w = 13701.66 g
