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
