To make a particular sweet substance, A concentrated sucrose solution is boiled until the temperature reaches 267ºF.

I don't know how can I find molality , they give me only temperature.
How can I molality, I think I need to find moles of solute and kg of solvent.
Please help

increase in Temp (must convert to C) = I(1 for sugar) x K X molality. K for water (boiling) is 0.51 C .

This gives you the amount over 100C = .51C x molality. Solve for molality. This is called a colligative property of a solution.

So, its going to be 196?

so, its gonna be 196??
196 What?
1) You must convert to C
2) Your temp is 130.6 C or 30.6 C above the normal boiling point
3) Your equation now is 30.6 C = (I)(K)(m)
4) Plug in your numbers 30.6 C = (1)(.51 C) (m)
5) Your molality is 60 or 60 moles per kilogram of water - a silly number - 20 kilos of sugar in 1 kilo of water. That is quite a syrup.
