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 L
x = 44.8 liters
Ideal gas law.
Pressure*Volume = moles*R constant*temperature in Kelvin
PV = nRT
(1 atm)(2.00 L) =n(0.08206 L*atm/mol*K)(298.15 K)
2.00/24.466 = moles N2
= 0.0817 moles nitrogen gas
====================
1 MOLE of gas occupies 22.4 Liters at STP so a 4 liter flask conatins 4/22.4 = 0.1786 moles
1 mole occupies 22.4 liters. So 2/22.4 = 0.0893 moles
4.00mol CO2 x 22.4L CO2/1mol CO2 = 89.6L CO2
use this formula, n(He)=m(He)/M(molar mass of He) =0.255G/4.OO =0.06375 moles per gram.
The answer is 14,93 moles.
How many moles are there in 9.0333x1024 atoms of helium
The answer is 0,2675 moles.
The answer is 2,7 moles.
use this formula, n(He)=m(He)/M(molar mass of He) =0.255G/4.OO =0.06375 moles per gram.
88.9237 moles
The answer is 14,93 moles.
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
The number of moles of helium is 0,32.
H2O or water doesn't have any helium in it.
The mass of helium equivalent to 0,775 moles is 3,102 g.
How many moles are there in 9.0333x1024 atoms of helium
How many moles of atoms are contained in 382 g Co
All of the moles of pure acid will have dissolved in the flask.
The answer is 0,2675 moles.
The answer is 2,7 moles.
