Question

Equal moles of h2o and nacl are present in solution the molality of nacl solution is

Answer 1

Molar mas of H2O = 18g/mol


Assuming the density of water to be 1g/ml

Volume occupied by 1 mole of water = Mass/Density

                                                           = 18/1 

                                                           = 18 ml


Volume in litres = 18/1000 = 0.018 Litres


Number of moles of NaCl = 1


Molarity of NaCl = Number of moles/Volume in litres


                          = 1/0.018

                          = 55.56 M

Answer 2

Answer:

Explanation:

Molar mas of H2O = 18g/mol

Assuming the density of water to be 1g/ml

Volume occupied by 1 mole of water = Mass/Density

= 18/1

= 18 ml

Volume in litres = 18/1000 = 0.018 Litres

Number of moles of NaCl = 1

Molarity of NaCl = Number of moles/Volume in litres

= 1/0.018

= 55.56 M
