What is the volume of gas 1 pound of dry ice will expand to as it sublimates?
Dry ice is CO2. Molar mass CO2 = 44 g/mole. 1 lb is approx. 454 g thus this = 454 g x 1 mol/44 g = 10.3 moles of CO2. At STP, 10.3 moles x 22.4 L/mole = 231 liters.
How many moles of carbon dioxide are in 10g of dry ice?
Dry ice is the solid form of Carbon Dioxide ( chemical formula : CO2 ) , comprising two oxygen atoms bonded to a single carbon atom . It is colorless , odourless , non - flammable , and slightly acidic. It is commonly used as a versatile cooling agent .
What mass of carbon dioxide is present in 1.00 m3 of dry air at a temperature of 25 ∘C and a pressure of 725 torr ?
113 PSU
How is CO2 dry cleaning better than PERC dry cleaning?
PERC dry cleaning produces percholorethylene, PCE, tetrachloroethylene, and tetrachloroethene which has been identified as a toxic contaminant and potential human carcinogen. CO2 does not produce these chemicals it is cleaner and greener.
Calculate the average molar mass of dry air if it has a density of 1.17 gL at 21oC and 740.0 torr?
To calculate the average molar mass of dry air, we can use the ideal gas law. Given that the density of dry air is 1.17 g/L at 21°C and 740.0 torr, we can calculate the molar mass using the formula: Molar mass = (dRT)/(P), where d is the density, R is the ideal gas constant, T is the temperature in Kelvin, and P is the pressure. Substituting the values and units, we can find the average molar mass of dry air.

Why dry ice CO2 floats?
CO2 floats because its density is less then water. Anything will float if its density is less then water. That is; when a certain volume of CO2 (or anything else) weighs less then the same volume of water.
Weight of a given volume of pure vapor or gas compared to the weight of an equal volume of dry air at the same temperature and volume?
PV = nRTAt a given temperature (T), pressure (P), and volume (V), the number of moles of gas is constant. Thus, whichever gas has a higher molar mass will weigh more. Air is composed of mostly Nitrogen gas (N2), Carbon Dioxide (CO2) and Oxygen gas (O2). The molar masses of these are 28, 44, and 32 respectively.If the pure vapor or gas in question is water vapor (H2O), with molar mass 18, then the air will weigh more.

What is solid CO2 called?
a molecular solid...
What is the molar mass of starch?
The molar mass of starch can vary depending on its composition, but on average, it is about 162 g/mol. Starch is a complex carbohydrate made up of repeating units of glucose molecules, which contribute to its molar mass.
What gas in dry air has 0.038 percent by volume?
Carbon dioxide (CO2).Actually, the level of CO2 in 2017 is 0.041%.Carbon dioxide makes up 0.041% of the atmosphere. The other main gases are 78.08% nitrogen, 25.95% oxygen, and 0.93% argon, with other trace gases.
