# Lesson Plan: Cryoscopic and Ebullioscopic Effects

In this lesson, we will learn how to use cryoscopic and ebullioscopic constants to calculate how solutes affect solution melting and boiling points.

#### Objectives

Students will be able to

- derive the formula for finding the area of a rhombus given the lengths of its diagonals,
- find the area of a rhombus given its diagonals,
- find unknown lengths of a rhombus using the formula for finding its area given the lengths of its diagonals,
- find the area of a square in terms of its diagonal,
- solve problems involving finding the area of both a square and rhombus using their diagonals.

#### Prerequisites

Students should already be familiar with

- finding the area of a square using its side length,
- find the area of a rhombus using its base length and height.

#### Exclusions

Students will not cover

- the Pythagorean theorem.
