SOLN 1
STP stands for Standard temperature and Pressure .
Standard Conditions are when temperature = 273.15 K
Standard Pressure = 1bar (105 Pa)
These are the two values at standard conditions.

Carbon dioxide (CO2) is collected ,in an inverted tube over water at 20oC and 760 mmHg.Determine the vapor pressure of water in the tube, and the partial pressure of the CO2.Then, use the ideal gas law (V/n = RT/P)to determine the CO2molar volume (V/n) in liters/mole at 20oC. 4.Suppose the quantity of CO2(44.0 g/mol) collected in problem 3 is 0.115 g. Convert this quantity to moles, then use the molar volume (V/n) from problem 3 determine the volume of CO2...

Name Dalton's Law of Partial Pressures - Many gas samples are a mixture of gases. For example, air is a mixture of gases. The gases dissolved in blood make up a mixture as well. In a gas mixture, each gas exerts its partial pressure (the specific pressure contribution of the gas to the total pressure of the gas mixture). Dalton's law states that the total pressure of a gas mixture (Pita) is the sum of the partial pressures of the...

PreLab Questions Gas Laws 1. In a mixture of helium and nitrogen the helium exerts a pressure of 0.65 atm and the nitrogen exerts a pressure of 1.50 atm. What is the pressure exerted by the mixture of the two gases? 2. Water vapor is water in the gaseous state. A gas that is collected over water will become saturated with water molecules because the water exerts a vapor pressure. The higher the temperature of the liquid water, the higher...
