Hint: To solve this question, first we have to understand the term density and buoyancy. Density is defined as the mass per unit volume.
Complete step by step answer:
Density is defined as mass per unit volume. With the use of density, we can calculate the kilograms of solvent using the litres of solution.
\[\rho =\dfrac{m}{V}\]
Where, $\rho $ is the density
M is the mass of the substance
And V is the volume
- And the buoyant force is directly proportional to density of the fluid in which the object is immersed. Buoyancy is the force or tendency to rise or float in a fluid. The upward force which is exerted on objects which are submerged in fluids are known as buoyant forces.
- The formula of the buoyant force is mentioned below:
F= $\rho $Vg = mg
Where, $\rho $ is the density
V is the volume of the liquid
M is the mass of the displaced fluid
And g is the value of acceleration due to gravity
This means that, denser will be the fluid i.e. more the density of the fluid more will be the buoyant force.
Additional Information :To calculate molality from molarity we will require the density of the given substance. If the density is given then it is easy to calculate molality from molarity. Density is defined as mass per unit volume. With the use of density, we can calculate the kilograms of solvent using the litres of solution.
Note: The density of the water of the dead sea is quite high. The buoyant force of the water of the dead sea will enable a person to float in water with ease.
