Question

Solution 1 has a greater density than does solution 2, and solution 1 also has a greater concentration of species A than does solution 2. For theses solutions, answer each of the following questions and support your answer:

1. Which will occupy greater volume: 1kg of solution 1 or 1 kg of solution 2?

2. Which will contain more molecules species A: 1 gallon of solution 1 or 1 gallon of solution 2?

3. If the two solutions flow with equal volumetric flow rate, which stream will have

a. the greater mass flow rate for the entire stream?

b. the greater molar flow rate of species A?

c. the greater mass flow rate of species A?

Explanation / Answer

1. Which will occupy greater volume: 1kg of solution 1 or 1 kg of solution 2?     

solution 2    because density=mass/colume

2. Which will contain more molecules species A: 1 gallon of solution 1 or 1 gallon of solution 2?

1 gallon of solution 1      bucause     density=mass/colume

3. If the two solutions flow with equal volumetric flow rate, which stream will have

a. the greater mass flow rate for the entire stream?    solution 1

b. the greater molar flow rate of species A?        solution 1

c. the greater mass flow rate of species A?           solution 1
