Determine the volume of the magnet and metal bolt to +/- 0.1 mL using units and sig figs carefully. Measure the mass and calculate the density of the magnet and metal bolt using the correct significant figures and units. Show work for full credit. (2 points)

45. You just removed 60,000 grams of 5.56 ammo from the stockpile of 167 kilograms. How manykilograms remain?

Predict: If the added mass on the lid was 50 kg, a total mass of 60 kg would exert pressure on the gas inside the container. What would be the volume of the gas? __.42 ______________

3. Find the number of atoms of each of the substances involved in the reaction.

Procedure: Have you made any changes to the procedure? Please explain. If you made no changes, state so. (1 point)

In your laboratory notebook sum these two reactions to find the stoichiometric factor that relates moles of

c. A lab exercise in BIO156 required 300 ml of water that was poured from a two-liter container. How many milliliters were left in the original container? (4 points)

Determine the VOC in Element A: You will need to multiply 2.8 pounds of VOC per gallon

In the scenario described in problem 7, what is the amount (in moles) of excess

The pressure of a gas sample increases for a decrease in volume and decreases for an increase in volume.

In Measuring and Understanding Density, several experiments were performed to find density of regularly shaped objects, irregularly shaped objects, liquids and gasses. An additional experiment was done to find the specific gravity of a sampling of liquids. The purpose of the experiment was to provide a better understanding of density and to be able to extrapolate unknowns based upon these calculations. The experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus its temperature. Key measurements and formulae were also used to determine densities of metal and plastic objects as well as irregularly shaped rocks. It is possible to find the density of an object (be it liquid, gas or

D. A sample of gold (Au) has a mass of 26.15 g. Given that the theoretical density is 19.30 g/mL,
