The osmotic pressure of a solution containing a solute with a molecular weight of 75,000 at a concentration of 30 g L-1 and a solute with a molecular weight of 20,000 at a concentration of 10 g L-1 and the solute with a molecular weight of 75,000 is unstable and completely dissociates into four solutes of equal size is calculated using the following .
steps;Step 1: Calculate the number of solute particles present in 30 g L-1 of the 75,000 g mol-1 solute that dissociates into four equal solutesIf the 75,000 g mol-1 solute dissociates completely into four equal solutes, each with a molecular weight of 75,000/4=18,750 g mol-1; then the number of solute particles in 30 g L-1 of the 75,000 g mol-1 solute will be:Number of solute particles = (30/75,000) × 6.022 × 1023 × 4= 0.00009622 × 1024 = 9.622 × 1018 particlesStep 2: Calculate the number of solute particles present in 10 g L-1 of the 20,000 g mol-1 soluteNumber of solute particles = (10/20,000) × 6.022 × 1023= 0.0003011 × 1024 = 3.011 × 1019 particlesStep 3: Calculate the total number of solute particles in the solutionTotal number of solute particles = 9.622 × 1018 + 3.011 × 1019= 3.9732 × 1019 particlesStep 4: Calculate the molar concentration of the solutionMolar mass of 75,000 g mol-1 solute (dissociated) = 18,750 g mol-1Molar mass of 20,000 g mol-1 solute = 20,000 g mol-1Molar concentration of the solution = (30/75,000) × 4 + (10/20,000) = 0.0008 mol L-1Step 5: Calculate the osmotic pressure using the formulaπ = nRT/Vwhereπ = osmotic pressuren = number of solute particlesR = gas constantT = temperatureV = volume of solutionπ = (3.9732 × 1019 × 8.314 × 293)/(1000 × 1000)= 7.46 × 105 PaTherefore, the osmotic pressure of the solution is 7.46 × 105 Pa.

To calculate the osmotic pressure of the solution, the final answer the osmotic pressure of the solution is approximately [tex]0.045[/tex]atm. We can use the formula: π = (n/V)RT,
where π represents the osmotic pressure, n/V is the concentration of the solute in moles per liter, R is the ideal gas constant, and T is the temperature in Kelvin. First, let's calculate the concentration of each solute:
For the solute with a molecular weight of [tex]75,000[/tex], which completely dissociates into four solutes of equal size:
Concentration = [tex]30[/tex] g/L [tex]/ (75,000 g/mol)[/tex] [tex]= 0.0004 mol/L[/tex]
For the solute with a molecular weight of 20,000:
Concentration = 10 g/L / (20,000 g/mol) = 0.0005 mol/L
Now, let's calculate the total concentration of the solutes:
Total Concentration [tex]= 4 * (0.0004 mol/L) + 0.0005 mol/L[/tex] [tex]= 0.0019 mol/L[/tex]
Using the ideal gas constant R = 0.0821 L·atm/(mol·K) and assuming a typical room temperature of 298 K, we can calculate the osmotic pressure: π [tex]= (0.0019 mol/L) * (0.0821 L·atm/(mol·K)) * (298 K)[/tex]
[tex]= 0.045 atm[/tex]

What
were some of the big philosophical differences amongst the Founder?
What are 3 smaller examples. Did this surprise you?
The Founding Fathers of the United States held various philosophical differences that influenced their perspectives on government, individual rights, and the structure of the new nation.
Here are three smaller examples of these differences, Federalism vs. Anti-Federalism: One significant philosophical difference was the debate between those favoring a strong central government (Federalists) and those advocating for stronger state sovereignty (Anti-Federalists). Federalists, such as Alexander Hamilton and James Madison, believed in a more centralized government with powers granted to the federal level. In contrast, Anti-Federalists like Thomas Jefferson and Patrick Henry were concerned about the potential for an overly powerful central government and emphasized the importance of states' rights. Strict Interpretation vs. Loose Interpretation of the Constitution, Another philosophical difference revolved around the interpretation of the Constitution.
