Is helium represented by he?
one mole of He
How many gram does one mole of helium gas weighs?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
How many moles of helium gas are contained in a 4.0-L flask at STP?
Because you're in STP conditions, you can use molar volume in a proportion. Molar volume is the volume one mole of an ideal gas will take up at STP: 22.4 liters/mole. To set up a proportion, think: if one mole of a gas occupies 22.4 liters, then 4.0 moles of a gas will occupy x liters.1 mole/22.4 L = 4.0 mole/X Lx = 44.8 liters
How many liters are in a mole?
One mole equals 22.4 liters. This is only at STP (Standard temperature and pressure!)
What has more mass one mole of helium or one mole of lead?
Lead. The molar mass of lead is 207.2 g/mol while helium's is 4.0 g/mol.
Is helium represented by he?
one mole of He
If a balloon contains 3.6 L of CH4 How many moles of gas are present at STP?
One mole takes 22.4l at STP.So 3.6l has 0.16mol
Ionization energy of a helium atom is helium gas per mole?
the first inoization energy is 2372.3 kJ mol-1 there are 6.0221415 × 10^23 in a mole from avagadros number, devide the ionization energy for one mole by the number of atoms in a mole and you get the first ionization energy for one atom.

How is the mole of a hydrogen the same asa mole of helium?
1 mole of all elements has 6.023 x 1023 atoms (but one mole of each element will weigh different)
What is a volume in liters of one mole of gas at STP first letter is a c?
Not sure what you mean by "first letter is a c", but the volume of one mole of an ideal gas at STP is 22.4 Liters.

How do you convert g mol to g L?
Mainly, you need to find out how many liters there are in a mole. This varies from one substance to another.
How many moles are there in 67.2 liters of carbon dioxide at STP?
There are always ONE mole of gas in 22,4 L gas of any kind (even gaseous mixtures like air) at stp.So 68.5 (L) / 22.4 (L/mole) = 3.06 mole gas in 68.5 L (at STP)
How many grams of methane gas CH4 are contained in a volume of 144 liters at STP?
One mole has amass of 16g.There are 6.428mol.Its mass is 102.85g
