a. Find the amount of solute based on this information
Volume = 500 ml
Concentration of solution= 15% (w/w)
Solute (molar mass) = H2SO4 is 98.0g/mol
b. Find the molar mass
Amount of solute= 117.0g
Volume of solution= 2.00L
concentration of a solution= 1.0M
volume of solvent = 2.00L
c. find the concentration of the solution (ppm) w/w
solute = 180g/mol(C6H12O6)
amount of solute= 0.0150mg
volume of solvent= 0.125L
d. find the volume of solvent
solute=60.0g/mol(CH3COOH)
amount of solute= 25.0 ml
concentration of solution= 5.00% v/v
I've answered this elsewhere.
a. To find the amount of solute based on the given information, we can use the formula:
Amount of solute = Volume of solution × Concentration of solution (w/w)
Given:
Volume of solution = 500 ml
Concentration of solution (w/w) = 15%
Convert the volume of the solution to liters:
500 ml = 500/1000 = 0.5 L
Now, substitute the values into the formula:
Amount of solute = 0.5 L × 15% (w/w)
b. To find the molar mass based on the given information, we can use the formula:
Molar mass = Amount of solute / (Volume of solution × Concentration of a solution)
Given:
Amount of solute = 117.0 g
Volume of solution = 2.00 L
Concentration of a solution = 1.0 M
Substitute the values into the formula:
Molar mass = 117.0 g / (2.00 L × 1.0 M)
c. To find the concentration of the solution (ppm) based on the given information, we can use the formula:
Concentration of solution (ppm) = (Amount of solute / Volume of solvent) × 10^6
Given:
Solute (molar mass) = 180 g/mol
Amount of solute = 0.0150 mg
Volume of solvent = 0.125 L
Convert the amount of solute to grams:
0.0150 mg = 0.0150/1000 = 0.0000150 g
Substitute the values into the formula:
Concentration of solution (ppm) = (0.0000150 g / 0.125 L) × 10^6
d. To find the volume of solvent based on the given information, we can use the formula:
Volume of solvent = Amount of solute / (Concentration of solution × 100)
Given:
Solute (molar mass) = 60.0 g/mol
Amount of solute = 25.0 ml
Concentration of solution (v/v) = 5.00%
Convert the amount of solute to liters:
25.0 ml = 25.0/1000 = 0.025 L
Now, substitute the values into the formula:
Volume of solvent = 0.025 L / (5.00% × 100)
