Answer:
Percentage of mass of solute in aqueous phase is 28.57%.
Explanation:
- Fraction of solute in aqueous phase.
= Used volume of aqueous solution
= Used volume of organic solution
D = partition coefficient.
Mass of solute in aqueous phase =
Therefore, Percentage of mass of solute in aqueous phase is 28.57%.
The acceleration of the car : 2.5 m/s²
<h3>Further explanation</h3>Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
∑F = m. a
<h3 />Mass of the car = 1200 kg
Forward force = 3400 N
Friction force = 400 N
The direction of motion of the friction force will be opposite to the forward force, so that both of them can be subtracted to get the value of the net force (net force: combination / sum of all forces acting on an object)
So the acceleration :
Answer:
Weight % of NH₃ in the aqueous waste = 2.001 %
Explanation:
The chemical equation for the reaction
Moles of HCl = Molarity × Volume
= 0.1039 × 31.89 mL ×
= 0.0033 mole
Total mass of original sample = 25.888 g + 73.464 g
= 99.352 g
Total HCl taken for assay =
= 0.1083 g
Moles of NH₃ =
= 0.03047 moles
Mass of NH₃ = number of moles × molar mass
Mass of NH₃ = 0.03047 moles × 17 g
Mass of NH₃ = 0.51799
Weight % of NH₃ = %
Weight % of NH₃ in the aqueous waste = 2.001 %
