0.50 M
Explanation:
Given data
- Mass of sodium sulfate (solute): 7.1 g
- Volume of solution: 100 mL
Step 1: Calculate the moles of the solute
The molar mass of sodium sulfate is 142.04 g/mol. The moles corresponding to 7.1 grams of sodium sulfate are:

Step 2: Convert the volume of solution to liters
We will use the relation 1 L = 1000 mL.

Step 3: Calculate the molarity of the solution

The given data is as follows.
Air is at
and 14.6 psia.
= 0.00015 ft, Flow rate, (Q) = 48000 
(a) Formula to calculate hydraulic radius
is as follows.

= 
=
ft
Formula for equivalent diameter is as follows.

=
=
ft
(b) Formula for velocity floe is as follows.
Q = VA
V = 
=
ft/min
= 24000 ft/min
(c) Formula to calculate Reynold's number is as follows.
= 
=
(as
and
= 0.0443 lb/ft. hr)
= 53742.66 hr/min
As 1 hr = 10 min. So, 
= 3224559.6
