Question

calculate the
more fraction of
Water when 5gm of water are
intumissed with 2gm of hy dungen​

Answer 1

mole fraction of water = 5/23

mole fraction of hydrogen = 18/23

We know,

if two substance are mixed,

then mole fraction of 1st substance is,

X1= n1÷ (n1 + n2)

mole fraction of 2nd substance is,

X2 = n2÷ (n1 + n2)

Here,

mole of Oxygen, n1= 5/18

mole of Hydrogen, n2= 2/2= 1

Therefore,

mole fraction of Oxygen is,

mole fraction of Oxygen is,X1=

$n1 \div (n1 + n2) \\ = (5 \div 18) \div ((5 \div 18) + 1) \\ = 5 \div 23$
