How many mmhg in 1 atm - Study guides, Class notes & Summaries

1. Question: A sample of oxygen gas has a volume of 3.52 L at 27°C and 800.0 torr. How many oxygen molecules does it contain? 2. Question: Consider a sample of gas in a container on a comfortable spring day. The Celsius temperature suddenly doubles, and you transfer the gas to a container with twice the volume of the first container. If the original pressure was 12 atm, what is a good estimate for the new pressure? 3. Question: Gas A and gas B are combined in a flask at initial pressures of 1...

CHEM 120 WEEK 8 Final Exam 2023 with correct answers Already graded A+ molarity = moles solute / liters solution 0.25 M = moles NaOH / 0.035 L moles NaOH = 0.00875 moles NaOH 1. (TCO 8) 35.0 mL of 0.25 M NaOH is neutralized by 23.6 mL of an HCl solution. The molarity of the HCl solution is (show your work): (Points : 5) 2. (TCO 1) How many mL are in 3.5 pints? Show your work. (Points : 5) 3.5 pints is equivalent to 1656.116 1 pint = 473.176 ml 3.5 pints* 473.176mL = 1656.116mL 3. (TC...

CHEM 219 – MODULE 3A PRACTICE PROBLEMS 1. A small bubble rises from the bottom of a lake, where the temp and pressure are 4°C and 3.0 atm, to the water's surface, where the temperature is 25°C and the pressure is 0.95 atm. Calculate the final volume in mL of the bubble if its initial volume was 2.1 mL. 2. Calculate the volume in liters occupied by 35.2 g of methane gas (CH4) at 25°C and 1.0 atm. R = 0.0821 L • atm/K•mol. 3. How many molecules of N2 gas can be present in a 2.5 L f...
