Answer:
THE MOLARITY OF SULFURIC ACID SOLUTION IS 0.05 L
Explanation:
Ca Va = Cb Vb
Ca = ?
Va = 75.0mL = 0.075 L
Cb = 0.150 M
Vb = 25.0 mL = 0.025 L
Ca = CbVb/ Va
Ca = 0.150 * 0.025 / 0.075
Ca = 0.00375 / 0.075
Ca = 0.05 M
The molarity is 0.05 L
Answer:
a. 4—ethyl—5—methyloctane
b. 2,2,6—trimethyloctane
Explanation:Please see attachment for explanation
Colligative properties depend on the amount of solute dissolved in a solvent. These set of properties do not depend on the type of species present. These properties include freezing point depression, boiling point elevation, osmotic pressure and vapor pressure lowering.
Answer:
Option-D: 2.3 × 10⁻³ mol/dm³
Explanation:
Calculate moles of ascorbic acid,
Moles = Mass / M.Mass
Moles = 0.080 g / 176 g/mol
Moles = 0.00045 mole
Also,
Molarity = Moles / Vol. in dm³
Molarity = 0.00045 mol / 0.20 dm³
Molarity = 0.00227 mol.dm⁻¹ or 2.3 × 10⁻³ mol/dm³
Answer:
The answer is D if it's wrong let me know pls
