Molarity is a unit of concentration expressed as the number of moles of dissolved solute per liter of solution. If the number of moles and the volume are divided by 1000, then molarity is expressed as the number of millimoles per milliliter of solution.

mass of water = 0.96 mol x 18.02 g/mol=17.3 g where 18 is atomic mass of water mass of ethanol = 0.040 x 46 g/mol =1.84 g now mass of solution = 17.3 + 1.84=19.1 g that is mass of water +mass of etanol Now assume that the density of the solution = 1g/mL so the volume ofsolution = 19.1 mL = 0.0191 L so finally the molarity will be

Relation Between Molarity And Molality What Is Molarity? Molarity is the concentration of a solution. It is also known as molar concentration. Molarity is the number of moles of solute per litre of solution. It is denoted by the symbol M. The formula is given below: M o l a r i t y = m o l e s o f s o l u t e l i t e r s o f s o l u t i o n

Chemistry Normality A solution of. Question A solution of H 3P O4 has a strength of 4.9% w/v. Find the normality of the solution. A 0.5 N B 0.3 N C 1.5 N D 0.5 N Solution The correct option is C 1.5 N 4.9% w/v means 4.9 g of H 3P O4 will be present in 100 mL of solution. Number of moles = given mass molar mass = 4.9 98 = 0.05

Molarity = M B×V A(mL)wB(g)×1000. = 18×720720×1000 = 55.5M. [720 g of water = 720 mL of water] .
