Question

a solution is prepared by dissolving 20g of NaOH in 1250ml of a solvent o​

Answer 1

Explanation:

Mass of solute =120g mass solution =1120g density of solution =1.15g / ml no. of moles of solute =12060 =2mol volume of solution

Answer 2

Answer:

Answer=2.05 M

Explanation:

Density of the solution 1.15gml-1=MV=1000+120V➡️V=11201.15=973.91mL

➡️Molarity=WMx1000VmL=120x1000x1.2

560x973.91=2.05M
