C . [x: 2 ,3 ,4 ,5 ,7 ,9 ]
In this item, we are going to use the concepts of total mass balance and component mass balance. We let the amount of the pure acid be equal to x.
Total mass balance:
7 + x = 7 + x
Hence, the total amount of the resulting solution is 7 + x
Component mass balance,
(1)(x) + (0.4)(7) = (0.7)(7 + x)
The value of x from the component mass balance is equal to 7.

Hence, the amount of cholesterol in 6 ounces of lobster will be 128.58 milligrams
Step-by-step explanation:
Given
Cholesterol in 3.5 ounces = 75 mg
Cholesterol in 6 ounces =x= ?
This can be worked out by using proportions
It can be written as:
![\frac{75}{3.5}=\frac{x}{6}\\21.43=\frac{x}{6}\\Multiplying\ both\ sides\ by\ 6\\21.43*6=x\\x=128.58\ mg](https://tex.z-dn.net/?f=%5Cfrac%7B75%7D%7B3.5%7D%3D%5Cfrac%7Bx%7D%7B6%7D%5C%5C21.43%3D%5Cfrac%7Bx%7D%7B6%7D%5C%5CMultiplying%5C%20both%5C%20sides%5C%20by%5C%206%5C%5C21.43%2A6%3Dx%5C%5Cx%3D128.58%5C%20mg)
Hence, the amount of cholesterol in 6 ounces of lobster will be 128.58 milligrams
