Question

What is the molarity of solution when 0.56 moles of sodium chloride is dissolved in 350

ml of water​

Answer 1

Answer:

1.6M

Explanation:

Volume = 350/1000 litre

Molarity = n/v

             = 0.56  x 1000 /350

              =  1.6M

Answer 2

Given :

➳ No. of moles of NaCl = 0.56

➳ Volume of solution = 350ml

To Find :

➨ Molarity of solution.

SoluTion :

➾ Symbol : M

➾ Definition : Number of moles of solutr dissolved in one litre of solution.

➾ Effect of Temperature : No

➾ Unit : mol/L

$\dashrightarrow\sf\:M=\dfrac{Moles\:of\:solute}{Volume\:of\:solution\:in\:L}$

$\dashrightarrow\sf\:M=\dfrac{0.56\times 1000}{350}$

$\dashrightarrow\underline{\boxed{\bf{\purple{M=1.6\:molL^{-1}}}}}\:\gray{\bigstar}$
