Volume to Volume Problems 1) Balance each combustion reaction equation and use volume ratios to determine the volume of oxygen needed to react with each fuel.
Intro to Gas Laws Student Practice Page. Instructions: List the variables down the left side, solve the equation for the unknown variable and write it on the left before substituting. 1. A 224 mL sample of argon had its pressure changed from 95.0 kPa to 185 kPa.
GAS VOLUMES 1. Volume (dm3) = 24 x moles. vol (dm3) 24 moles. The volume must be in dm3 (there are 1000 cm3 in 1 dm3). vol in dm3 = vol in cm3 1000. Give all answers to 3 significant figures. 1 . Find the volume of the following gases (measured at room temperature and pressure). 2 . 4.00 moles of oxygen (O2)
What volume will the gas occupy at STP? At a certain temperature, molecules of methane gas, CH4 have an average velocity of 0.098 m/s. What is the average velocity of carbon dioxide molecules at this same temperature? Find the relative rate of diffusion for the gases chlorine, Cl2 and ethane, C2H6.
A sample of gas has a mass of 0.501 g. Its volume is 0.425 L at a temperature of 110 oC and a pressure of 1120 mmHg. Find its molar mass. Solutions. How many moles of gas (air) are in the lungs of an adult with a lung capacity of 3.9 L? Assume that the lungs are at 1.00 atm pressure and at a body temperature of 40 oC. (Hint: V, P, and T are given.
Use your knowledge of the ideal and combined gas laws to solve the following problems. If it involves moles or grams, it must be PV = nRT. 1) If four moles of a gas at a pressure of 5.4 atmospheres have a volume of 120 liters, what is the temperature? 1973 K.
