25.5g C7H11NO7S (4-nitro-2-toluenesulfonoic acid dihydrate) in 1.00*10^2g H2O (nonionizing solute)
And the question is?
whats the answer
To understand the solution you have provided, we need to break it down into its components.
1. Solute: The solute in this case is 25.5 grams of 4-nitro-2-toluenesulfonoic acid dihydrate (C7H11NO7S). This compound is a solid and will dissolve in the solvent.
2. Solvent: The solvent is 100.0 grams of water (H2O). Water is commonly used as a solvent because it has a high polarity, meaning it can dissolve many substances.
Now, based on the given information, we can calculate a few properties of the solution.
1. Total Mass: The total mass of the solution can be calculated by adding the mass of the solute and the mass of the solvent.
Total mass = Mass of solute + Mass of solvent
= 25.5 grams + 100.0 grams
= 125.5 grams
2. Concentration: The concentration of the solution can be calculated by dividing the mass of the solute by the total mass of the solution and multiplying by 100 to express it as a percent.
Concentration (%) = (Mass of solute / Total mass of solution) × 100
= (25.5 grams / 125.5 grams) × 100
= 20.3%
3. Molarity: Molarity represents the number of moles of solute present in one liter of the solution. To calculate the molarity, we need to convert the mass of the solute into moles and then divide it by the volume of the solution in liters.
Moles of solute = Mass of solute / Molar mass of solute
= 25.5 grams / (Molar mass of C7H11NO7S)
The molar mass of C7H11NO7S can be calculated by adding the atomic masses of each element:
C (12.01 g/mol) × 7
H (1.008 g/mol) × 11
N (14.01 g/mol) × 1
O (16.00 g/mol) × 7
S (32.07 g/mol) × 1
Once you have the molar mass, you can calculate the moles of solute. To find the molarity, you will also need the volume of the solution in liters.
Please note that you haven't provided the volume of the solution in the given information, so we cannot calculate molarity without that information.
