An unknown gas with a mass of 8.32 g is held at 25 degrees Celsius in an 8.42 L tank under 1147.6 mmHg pressure What is the molar mass of the gas?
0.52 mol.
What is the mass of water at 25 degrees Celsius if the volume of water is unknown?
Question makes no sense - unanswerable. Nothing changes mass when heated or cooled.
How cold is charon?
The temperature of Charon is still unknown but we do know that it is farther from the sun the Pluto so it must be colder then -223 Celsius
What is the pressure in ATM exerted by 25.0 grams of XeF6 in a 5 liter container at 25 degrees Celsius?
Use the Ideal Gas Law: PV=nRT (pressure times volume equals moles times the ideal gas constant of 0.082 times the Kelvin temperature.) First, convert 25 Celsius to Kelvin: 25+273=298. Next, find out how many moles is in 25.0g of XeF6: 1(Xe)+6(F)=1(131.3)+6(19)=245g/mol; 25g XeF6=0.102mol. Then, plug it all in and solve for the pressure, which is your unknown: P(5L)=0.102mol(0.082)(298kelvins) Simplify: 5P=2.4925, P=0.4985, or approximately 0.5 atm of pressure.
The atmospheric pressure on earth is 1.0 ATM What is it on Venus?
the atmospheric pressure on the surface of venus is very unknown but i am the scientist that knows all haha lol but really it is 90 degrees fahneiht

0.52 mol.
What is the significance of temperatures between -6 degrees Celsius to -18 degrees Celsius?
The temperature -6 °C is about 21.2 °F, so the significance is unknown, but -18°C is the metric approximation of 0°F(actually equals 0.4°F).
What is the mass of water at 25 degrees Celsius if the volume of water is unknown?
Question makes no sense - unanswerable. Nothing changes mass when heated or cooled.
A container of oxygen at 22 degrees Celsius and 740mm Hg is cooled to -22 degrees Celsius What is the new pressure of the gas?
Formula:P1 P2---- = ----T1 T2P1= 740 mm HgP2= UnknownT1= 22°C= 295 KT2= -22°C= 251 K740 / 295 = P2 / 251P2= 630 mm Hg
If Celsius is based upon water's melting point 0 degrees Celsius and water's boiling point 100 degrees Celsius what is Fahrenheit based upon?
In Fahrenheit, 32°F is the freezing point of the water and the boiling point is 212°F. Fahrenheit for unknown reasons calibrated his scale so that 0 was the freezing point of salt water and 100 was the internal temperature in his mouth.
What happens when collected all unknown fire red?
nothing
