- A gas cloud of molecular hydrogen has a temperature of 100 K and a number density of 100 molecules per cubic centimeter. What mass (in solar masses) must the gas cloud be in order to collapse? (Do not enter the unit into the answer. Just enter the number.) (it is not 1800 or 3300)arrow_forwardCalculate the volume of carbon dioxide gas that is collected. You can assume the pressure in the room is exactly 1atm. Round your answer to 3 significant digits.arrow_forwardThe circus clown is a chemistry geek and likes to fill his balloons to exactly 30 moles of helium to each ballon. The balloons start with .008 moles of helium and a volume of .0012 liters. Assuming the pressure and temperature remain the same how much volume will his balloons be once they are full? (Round your answer to 1 decimal place and don't forget units.)arrow_forward
- A balloon filled with 0.264 moles of argon gas had a volume of 13.1 L. If 0.448 moles of argon were added to the balloon, what would be the new volume (in L to 1 decimal place)? What are the units?arrow_forwardWhat is the other name of the specific gravity bottle? What is the reference standard for gases? What is the environment in assessing relative density? What is the preferred unit for specific volume? What is the temperature (in degrees Celsius) at which pure water has its highest densityarrow_forwardcan you please explain how we get the cumulative volume and what is it? The image below is just for reference. It shows the cumulative volume. But do we obtain itarrow_forward
- Two groups did an Experiment with exactly the same mass of Mg, temperature, and barometric pressure. Group X used a 50-mL eudiometer while Group Y used a longer 100-mL eudiometer. After the experiment, both groups observed a Case A scenario. Additionally, they noted that the group using the longer eudiometer recorded a higher h. How would the volume readings in their eudiometers compare?arrow_forwardUse the formula provided to find out the calculated volume of each cylinder.arrow_forwardFluorine gas and water vapor react to form hydrogen fluoride gas and oxygen. What volume of oxygen would be produced by this reaction if 9.11 L of fluorine were consumed? Also, be sure your answer has a unit symbol, and is rounded to the correct number of significant digits.arrow_forward
- In a laboratory, two gases are simultaneously injected into cylinders with movable pistons. 15 minutes after injecting the gas into the cylinders, the mass and volume of the two samples are determined. The results of these measurements are shown in the table below. Which of the following is a correct conclusion drawn from these data?arrow_forwardAt STP, a sample of helium gas occupies a balloon to a volume 2.7 Liters. How many moles of helium gas are in the balloon? Express your answer to the correct number of significant figures, and include units with your answer.arrow_forwardConvert the following units s (state any assumptions you have to make to do the calculations): 380 ppm = X ppt 100 ppt = X molec/cm3 230 ppb = X moles/larrow_forward
