The volume of HCl gas required to prepare the solution is 101.54 L
<h3>How to determine the mole of HCl </h3>
- Volume of solution = 1.25 L
- Molarity = 3.20 M
- Mole of HCl =?
Mole = Molarity x Volume
Mole of HCl = 3.2 × 1.25
Mole of HCl = 4 moles
<h3>How to determine the volume of HCl </h3>
- Number of mole (n) = 4 moles
- Temperature (T) = 30 °C = 30 + 273 = 303 K
- Pressure (P) = 745 torr = 745 / 760 = 0.98 atm
- Gas constant (R) = 0.0821 atm.L/Kmol
Using the ideal gas equation, the volume of the HCl gas can be obtained as follow:
PV = nRT
Divide both side by P
V = nRT / P
V = (4 × 0.0821 × 303) / 0.98
V = 101.54 L

From the information given, Michelle belongs to the cooking lifestyles segment called: "TrendSetters"
<h3>What are food lifestyle segments?</h3>
Lifestyle segmentation is the commercial technique of grouping potential or present consumers into groups known as market segments based on lifestyle criteria such as purchasing preferences.
The idea is to target one or more lifestyle categories with your marketing mix.
With this in mind, Roy Morgan Research created Food Segments, a market segmentation technique that categorizes individuals based on their food and culinary views.
