Count the concentration ofthe solution as a result ofadding 3Liter H20

1.	Count the concentration ofthe solution as a result ofadding 3Liter H20 to thesolution of HCl containing0.2 Litre 5M concentration.
Answer» given the concentration of HCL = 5M so , no of moles of HCL = 5*0.2 = 1mol now, when 3 litres of water are added.. then total volume will be 3+0.2 = 3.2L so , new concentration = mol/vol = 1/3.2 = 0.3125M

Count the concentration ofthe solution as a result ofadding 3Liter H20 to thesolution of HCl containing0.2 Litre 5M concentration.

Answer»

given the concentration of HCL = 5M

so , no of moles of HCL = 5*0.2 = 1mol

now, when 3 litres of water are added.. then total volume will be 3+0.2 = 3.2L

so , new concentration = mol/vol = 1/3.2 = 0.3125M
