Molarity/ molar is a unit of concentration, symbolized by "M". It is the ratio of the number of moles of solute and the volume of solution.
Molarity = Moles of solute ÷ Liters of solution = moles/liter = M
molarity is define as the number of mole of a solute in 1 liter of solution
Find volume of pillow
L=78cm
B=55cm
H=25cm




Now
Mass=5.5kg



Density of water=1000kg/m^3
As it is less than density of water it will float on water
Answer:
<em>An electrical circuit is an unbroken path along which an electrical current occurs and/or will pass. The basic electrical circuit consists of a power supply, two conductive wires (one end of each being connected to each cell terminal) and a small light to which the free ends of the wires leading out of the cell are attached. If the links are made right, the circuit will "close"</em>
Explanation:
In chemistry, water(s) of crystallization or water(s) of hydration are water molecules that are present inside [crystal]s. Water is often incorporated in the formation of crystals from aqueous solutions. ... Water of crystallization can generally be removed by heating a sample but the crystalline properties are often lost
