The boiling point of a solution of 0.1050 g of a
substance in 15.84g of ether was found to be 0.1⁰c
higher than that of ether. What is the molar mass of
the substance ? (kb = 2.02 k kg/mol)

Explanation:
Angles, parallel lines and transversals
Two lines that are stretched into infinity and still never intersect are called coplanar lines and are said to be parallel lines. The symbol for "parallel to" is //.
If we have two lines (they don't have to be parallel) and have a third line that crosses them as in the figure below - the crossing line is called a transversal:
Transversal
In the following figure:
Angles
If we draw to parallel lines and then draw a line transversal through them we will get eight different angles.
The eight angles will together form four pairs of corresponding angles. Angles F and B in the figure above constitutes one of the pairs. Corresponding angles are congruent if the two lines are parallel. All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs.
