Question

1 molal solution of sodium chloride has a density of 1.21 g/ml.the molarity of this solution is​

Answer 1

Answer:

here you go...

Explanation:

Molal solution = 1 mole of NaCl contains 1000gm of water solution.

1 mole NaCl = 58.5 gm NaCL

So 58.5 of NaCl contains 1000g of water solution.

The total mass = 1000+58.5=1058.5

density = mass/ volume

volume= m/d=1058.5/1.21=874.7933

molarity = no. of moles/ volume = 1/874.7933=0.001143.
