42. Of 6.5 hectoliters of fuel, the private spilled 350 milliliters. How many liters did the private spill?

(a) What is the capacity (saturation missing ratio) of the rising air at 3000 feet?

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 ______________

1. The pressure announced on last night's television weather broadcast was 29.92. Explain how this was measured and give the units. Would this be considered an unusually large or low pressure value?

Can I apply this somehow to volume? Well at standard temperature and pressure (STP) a mole of a gas will occupy 22.4 liters. So If we keep our units straight we should be able calculate a given volume of gas from moles. Check it out…… http://www.sciencegeek.net/Chemistry/Video/Unit4/GMV4.shtml

d. A typical can of soda is 355 ml. How many liters are there in this can of soda? (4 points)

6. Restate your predictions that were correct and give the data from your experiment that supports them. Restate your predictions

Determine the VOC in Element B: You will need to multiply 1.2 pounds of VOC per

Step 1: The volume of the quarter-sphered tank rounds up to 478,676. You use the condition to find the volume.

3. The volume of a fixed mass of a liquid sample increases as the temperature rises from 20 to

28) A basketball is inflated to a pressure of 1.90 atm in a 24.0°C garage. What is the pressure of the basketball outside where the temperature is -1.00°C? A) 2.08 atm B) 1.80 atm C) 1.74 atm D) 2.00 atm 29) The density of a gas is 1.43 g/L at STP. What is the gas? A) Cl2 B) O2 C) S 30) Zinc reacts with aqueous sulfuric acid to form hydrogen gas: Zn (s) + H2SO4 (aq) → ZnSO4 (aq) + H2 (g) In an experiment, 201 mL of wet H2 is collected over water at 27°C and a barometric pressure of 733 torr. The vapor pressure of water at 27°C is 26.74 torr. The partial pressure of hydrogen in this experiment is __________ atm. A) 1.00 B) 706 C) 0.929 D) 0.964 E)

We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL.

A chemistry teacher has 2,342 grams of a substance and he wants to separate the substance into 7-oz jars. How many 7-oz jars can he fill?

The Acme Life Preserver Company needs to fill up a position within their company and they want to develop a new line of life preserves that inflate when the seal is broken with two mixing chemicals. Applicants must formulate and test a formula that gives the volume of the life preserver with the smallest amount of sodium bicarbonate that mixes with an excess of 1.0 M HCl and pressure of 1300 torr to inflate the life preserver. The balanced equation used to determine the volume of the life preserve

2. Note that the balloon in the chamber is filled with 0.300 moles of an
