Question

to make saturated solution 37 g of aluminium chloride is dissolved in 100 g of water at 293 k . find its concentration at this temperature .

Answer 1

Answer:

Mass of solute(AlCl3)= 37 g

Mass of solvent(water)= 100 g

Mass of solution= mass of solute + mass of solvent

= 37 + 100

= 137 g

concentration= mass of solute/ mass of solution× 100

= 37/137×100

= 0.27×100

=27%

Answer 2

Answer:

$Mass of sodium \: chloride (solution) = 36 g \: Mass \: of \: water (solvent) = 100 g \: Total \: mass of solution = 100 + 36 = 136 g \: Mass \: percentage \: of solution= mass \: of \: solute \: / \: mass \: of solution X 100 =36/136x100 = 26.47%Massofsodiumchloride(solution)=36gMassofwater(solvent)=100gTotalmassofsolution=100+36=136gMasspercentageofsolution=massofsolute/massofsolutionX100=36/136x100=26.47$
