Molarity is number of moles of solute per one liter of solution. The symbol for molarity is a capital M. The molarity of the given solution will be 3.125M
A solution is a mixture of two or more substances in which neither of substance changes chemically. For example, the salt water is a solution that contains the water (the solvent) and salt (the solute). Concentration is amount of dissolved substance in a solution. In other words, it is amount of stuff that has been mixed into the liquid. Concentration is usually measured in the molarity.
Given that,
Number of moles= 1
Volume = 320ml= 0.320 L
Molarity= No of moles of solute/ Volume of solution in L
= 1/ 0.320
= 3.125 M

Answer: for an object or gas or liquid to float in another there must be a difference in density
Explanation:
Helium has a density of 0.18 kg/m³ and air has a density of 1.29 kg/m^³. If a balloon is filled with helium it will float in air due to density differences
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces
