The correct Answer is 76.8
The Latin American Wars of Independence, which took place during the late 18th and early 19th centuries, were deeply influenced by the American and French Revolutions and resulted in the creation of a number of independent countries in Latin America.
Two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.
<h3>What is couple?</h3>
Couple is the pair of force of equal magnitude which acts in opposite direction to each other. The moment of couple is known as the troque, which can be calculate as,

Here, (F) is the magnitude of one of the force and (s) is the perpendicular distance of force acting on axis.
Here, the two opposite forces are given which acts perpendicular to an axis. Now suppose there is the magnitude of both the force (F) is equal and the perpendicular distance from the axis is also same.
Thus, from the above definition of moment of couple, they produce, torque or moment of couple.
Hence, the two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.

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

The attached graph shows the required curves to be drawn. One of the curves is called the Marginal Revenue Curve.
<h3>What is a marginal revenue curve?</h3>
At the market price, the marginal revenue curve is a horizontal line, suggesting completely elastic demand, and it is equal to the demand curve.
