Calculate the value of
obtained at
hcl from
8.85g of
of Nacl

Explanation:

5.85g of nacl ,

molecular mass of nacl is 58.44 approx.

therefore no. of moles of nacl are 0.1

and 90g of water,

molecular mass of water is 18

therefore no. of moles are 5

mole fraction=no.of moles of nacl / no. of moles of nacl +no. of moles of water.

mole fraction = 0.1 / 0.1+5

=0.1/5.1

= 1 / 51. ( Ans )

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
