HEY THERE

2.) given- WB=60g , WA=250g , kf=1.86 , MB=108g

formula given-

delta \: tf  = \frac{kf \times wb \times100 }{mb \times wa}

we get,

deta \: tf =  \frac{1.86kg \: per \:  {mol}^{ - 1}  \times 60g \times 1000g \: kg^{ - 1} }{108 g {mol}^{ - 1}  \times 250g}

delta \: tf = 2583.33k

freezing point of the solution,

tf= T knot f-delta Tf

=273.15-2583.33

=1310.18k

HOPE IT HELP

#i will edit my answer when i got another question #

^_^

Avanish010: it's ok.. i have done
Avanish010: 15*
Anonymous: ok that's great ^_^
Avanish010: why u substract 275.15 ??
Anonymous: initially freezing point 0 degree Celsius
Anonymous: i.e. 273.15K
Avanish010: thanks

mb×wa

kf×wb×100

delta \: tf = 2583.33kdeltatf=2583.33k

freezing point of the solution,

tf= T knot f-delta Tf

mark me plz

=273.15-2583.33

=1310.18k
