Question

if 5.85g of Nacl are dissolve in 90g of water the mole fraction of nacl is

Answer 1

Hello friend

Solution :

=> given mass of NaCl = 5.85 g

So moles = 5.585 / 58.5

=> 0.1 mol

And

Given mass of water = 90 g

So moles =>90 / 18

=> 5 moles

Mole fraction of NaCl

= > moles ( Nacl) / total moles

=> 0.1 / 0.1 + 5

=> 0.1 / 5.1

=> 0.0196

So the mole fraction of NaCl is 0.0196

Answer 2

5.85g of NaCl are dissolved in 90g of water. The mole (c) 2 fraction of NaCl is

therefore answer is

mole fraction of NaCl is 0.0196
