Answer:
Density of the liquid = 1470.43 kg/m³
Explanation:
Given:
Mass of solid sphere(m) = 6.1 kg
Density of the metal = 2600 kg/m³
Thus volume of the liquid :
Volume of the sphere = 6.1 kg/2600 kg/m³ = 0.002346 m³
The volume of water displaced is equal to the volume of sphere (Archimedes' principle)
Volume displaced = 0.002346 m³
Buoyant force =
Where
is the density of the fluid
g is the acceleration due to gravity
V is the volume displaced
The free body diagram of the sphere is shown in image.
According to image:
Acceleration due to gravity = 9.81 ms⁻²
Tension force = 26 N
Applying in the equation to find the density of the liquid as:
<u>Thus, the density of the liquid = 1470.43 kg/m³</u>
Answer : The equilibrium concentration of is, 0.50 M
Explanation : Given,
Initial moles of = 0.65 mole
Volume of solution = 1.0 L
Moles of at equilibrium = 0.15 mole
The balanced equilibrium reaction will be,
Initial moles 0.65 0 0
At eqm. (0.65-x) x x
Moles of at equilibrium = x = 0.15 mole
Moles of at equilibrium = x = 0.15 mole
Moles of at equilibrium = (0.65-x) = (0.65-0.15) = 0.50 mole
Now we have to calculate the concentration of at equilibrium.
Formula used :
Therefore, the equilibrium concentration of is, 0.50 M
