What volume is occupied by 1.00 kg of helium at 5.00 degrees celsius at a pressure of 735 torr?

Well, we might as well convert all of this mess. ( we could work in Torr, but why when we are mass converting )
1.00 kg He (1000 grams/1 kg) = 1000 grams He (1 mole He/4.003 grams) = 250 moles He
5.00o Celsius = 278.15 Kelvin
735 Torr = (1 atm/760 Torr = 0.967 atmospheres
=========================================Now,
PV = nRT
(0.967 atm)(Volume) = (250 moles He)(0.08206 L*atm/mol*K)(278.15 K)
0.967V = 5706.247
Volume = 5.90 X 103 Liters

Liquid helium has a boiling point of 4.2 k What is that in Celsius?
4.2 Kelvin is -268.95 degrees Celsius.
Can helium be compressed?
no, it can not be compressed.
What is the temperature of -273 degrees C?
This temperature is impossible! You must mean -273 degrees CELSIUS (centigrade if you are in the USA). Your "k" implies the KELVIN (K) scale of temperature, which starts at 0 K which is -273 degrees Celsius (C). Both scales change similarly - 1 degrees Celsius = 1 Kelvin (NOTE: NOT degrees Kelvin). At -273 degrees Celsius ALL particle motion has stopped. Ice would have formed well before this temperature - about 270 degrees before!
What is helium's freezing point?
Well, everything has its own unique freezing/melting and boiling. Helium, has a freezing/melting point of -310 degrees Celsius, or in other words, when it is below -310 it is a solid and when it is above -310 it is a liquid.
What is the melting point of helium in kelvin?
.8 degrees Kelvin
What is the density of helium at 25 degrees celsius and one atmosphere of pressure?
WATER
The freezing point of helium is -272 degrees Celsius The original temperature of a sample of helium is 3 degrees Celsius how much must the temperature change to ensure that helium freezes?
275 degrees
What is the the melting point of helium?
-1480 degrees Celsius
What is the melting point and the boiling point of helium in degrees Celsius?
Helium melts at −272.20 °C and boils at −268.93 °C
What is helium like at 20 degrees?
it is a colourless odourless gas at 20 degree Celsius
What is that something really cold?
Liquid helium, it liquefies at -230 to -240 degrees Celsius.
How much heat does it take to melt helium?
To melt helium, it requires extremely low temperatures rather than heat. Helium becomes a liquid at temperatures below -268 degrees Celsius (-450 degrees Fahrenheit) and does not require significant amounts of heat to transition from its gaseous state to a liquid state.
Which element would boil only 1 degrees Celsius after it melted?
Helium!! :)
What is the boiling point of Heluim?
The boiling point of helium is -268.9 degrees Celsius.That would be -452.02 degrees Fahrenheit.
A mixture of methane and helium is placed in a 2.0 l flask at 27 degrees the partial pressure of mathane is 0.72 ATM and the partial pressure of helium is 0.22 ATM What is the mole fraction of ch4?
0.77
Liquid helium has a boiling point of 4.2 k What is that in Celsius?

What happens when a medium star's temperature reaches 200000000 degrees Celsius?
helium atoms fuse to form carbon atoms in the core of the star
