Question

1. To what volume would you have to change 12.0 L of gas at 989.4 kPa in order to decrease its pressure to 33.0 kPa. Assume no temperature change occurs. 33.0 98 94 x 12 2. A container filled with 6.7 mols of gas at 343 K and a pressure of 340 kPa will have what volume 3. What is the approximate temperature of neon gas in a 25.0 g sample that exerts a pressure of 0.922 atm and has a volume of 3.25 L? 4. A sample of oxygen gas occupies a volume of 436.2 mL at 1.02 atm. If the temperature is held constant, what would the pressure of this gas be when the gas is compressed to 231.6 mL? 5. A gas takes up a volume of 17 liters, has a pressure of 2.3 atm, and a temperature of 299 K. If I raise the temperature to 350 K and lower the pressure to 1.5 atm, what is the new volume of the gas? 6. A gas was found to have a mass of 0.88g with the volume of 0.500L at 24.0°C and a pressure of 0.958 atm. What is its molecular mass? 7. What volume will 1.27 moles of helium gas occupy at STP?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied.

In statistics, a frequency distribution is a list, table or graph that displays the frequency of various outcomes in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval.
