Flask A contains 2 liters of ch4 g and flask B contains 2 liters of o2 g each gas sample has the same?
number of molecules
In which layer are most gas molecules found?
no
How many molecules of N2 gas are in a 500.0ml sample at 780mmHg and 135 C?
4.9x10^22 molecule
Which quantity of o2 contains exactly 3.01x1023 molecules?
3,6 x 1023 molecules of oxygen gas O2 are equivalent to approx. 0,6 moles.
What is the gas composition range of stratosphere?
Stratosphere contains the ozone layer. The ozone layer is mostly composed of ozone molecules.
Flask A contains 2 liters of ch4 g and flask B contains 2 liters of o2 g each gas sample has the same?
number of molecules
At a certain temperature and pressure 0.02 mol of carbon dioxide has a volume of 3.1 L A 3.1 L sample of hydrogen at the same temperature and pressure?
contains the same number of molecules
How many types of molecules with different masses exist in a sample of chlorine gas if the same exists entirely as diatomic molecules?
3
Where is most of the gas molecules in the atmosphere found?
The atmosphere is made of gas molecules.
If a balloon contains 0.15 moles of CO2 gas. how many molecules of CO2 are in the balloon?
The number of molecules is 0,90332112855.10e23.
Chlorine gas is a diatomic molecule Cl2. There are 6.00 mol of chlorine atoms in a sample of chlorine gas. How many moles of chlorine gas is this?
there are 6 molecules of chlorine gas
How many oxygen molecules are in 9.1 L of oxygen gas at STP?
at stp 1 mole of a gas contains 22.4 litres. 9.1/22.4= .40625 moles o2. 1 mole of a gas contains 6.022E23 molecules so .40625 moles x 6.022E23 = 2.4464325E23 molecules, but you have to multiply by two due to it being diatomic, so answer x 2 = 4.892875E23 molecules
Which material has the most loose molecules?
A gas.
In which layer are most gas molecules found?
no
The diagram represents four 500-milliliter flasks Each contains the gas represented by the symbol All gas samples are at STP Each flask contains the same number of?
Molecules only.
How many molecules of N2 gas are in a 500.0ml sample at 780mmHg and 135 C?
4.9x10^22 molecule
In brief what is a vacuum?
A vacuum is a space that contains very few molecules of gas, which results in a very low pressure.
