00:01 Hello students here in this question we have given the molality here i is equals to 1 and kf is equals to 1 .86.
00:09 Here we are having formula delta t f is equals to i kf into molality.
00:18 So we have given 0 degrees celsius minus x and i is here 1 into k f is 1 .86 into the molality that is 0 .2.
00:29 So minus x is equals to 0 .372...
