1. molar mass of Cl2 = 2(35.45) = 70.90 g/mole
2. Molar volume is the volume when n = 1.00 mole.
V = ?; n = 1.00 mol; T = 78C + 273 = 351 K; P = 1.20 atm
3. V1 = 6.

The Relationship Between Ramp Height and Acceleration
Objective: The purpose of this experiment is to determine the acceleration due to gravity in
relation to the height of the ramp.
Stopwatch: Because its a digital item, its tool uncert
The Relationship Between Distance and Time on Speed
Objective: The purpose of this experiment is to determine the average speed of a toy car (Blue
#8) and to evaluate if the speed is constant through its run.
Tool uncertainty: 0.01
This lab was a success because, all three parts worked as either a 2/3 or 3/3
success. We had three different experiments to work with. The first one should end up
moving a very loud popping noise, the second one should put the flame out, and the

Stoichiometry is a section of chemistry that involves using relationships between
reactants and products in a chemical reaction to determine desired quantitative data.
Stoichiometry helps you figure out how much of a compound you will need, or mayb

In this lab we hope to prove how to write electron configurations for 10
elements(boron, silicon, sulfur, calcium, arsenic, iodine, rubidium, chromium, gallium,
and platinum) using orbital filling diagrams and electron dot diagrams. These three
