By definition if Molarity we know that it is the no. of moles present in per litre of solution. = 1M molar solution has 1 mole of NaNO
By definition if Molarity we know that it is the no. of moles present in per litre of solution. = 1M molar solution has 1 mole of NaNO 3
By definition if Molarity we know that it is the no. of moles present in per litre of solution. = 1M molar solution has 1 mole of NaNO 3
By definition if Molarity we know that it is the no. of moles present in per litre of solution. = 1M molar solution has 1 mole of NaNO 3 for 1000ml of solution.
Therefore, mass of solute is mass of 1 mole of NaNO
3
3
3 = 23+14+48 = 85 gm.
3 = 23+14+48 = 85 gm.
volume of solution = 1000 ml
as per definition.
as per definition.Now,Given that density is 1.25 g/cm3
Therefore, mass = 1.25×1000 (m = density X volume)
=> mass = 1250 gm (solution mass)
Mass of solvent = mass of solution - mass of solute
Mass of solvent = mass of solution - mass of solute = 1250 - 85= 1165gm.
Mass of solvent = mass of solution - mass of solute = 1250 - 85= 1165gm.
Mass of solvent = mass of solution - mass of solute = 1250 - 85= 1165gm.
Mass of solvent = mass of solution - mass of solute = 1250 - 85= 1165gm. =0.85m
