atoms have a higher mass than molecules. Because both gases at STP have the same number of molecules per unit volume, the gas must be denser.

Is nitrogen a solid at stp?
No. Nitrogen is a gas in atmosphere, the air we breathe.
Which group 15 element exists as diatomic molecules at STP?
nitrogen
Which 2 elements are gases at STP?
hydrogen, nitrogen, oxygen, fluorine, and chlorine are all gases at STP
How much nitrogen is present in 4.000 liters of air?
Roughly 3.123 liters (at the same pressure). Nitrogen is 78.08% of dry air by volume. 3.123 liters of nitrogen at STP is about 0.14 moles, or just under 2 grams.
What state of mater is nitrogen?
At standard Tempoeratures and Pressures(STP) nitrogen state of matter is a GAS . However it can be cooled to form a liquid and further cooled to form a solid, but these are extremely low temperatures.
Why is hydrogen less dense than water?
At standard temperature and pressure (STP) hydrogen is a gas and water is a liquid.
Is nitrogen lighter than air?
If you are asking whether nitrogen is less dense than air and will float on top of it, then yes, nitrogen is "lighter," albeit only slightly. More accurately, nitrogen, which is a constituent gas of air, is less dense than air, not lighter. The density of air at standard temperature and pressure is 1.292 kg/m3. The density of nitrogen is 1.251 kg/m3.
Why is water less dense than frost?
Water is more dense than frost. Frost is ice, which is less dense than water. Siress: While this is true, frost can also be an agglomeration of ice particles in which large voids of trapped air can cause the density of the mass to be less than that of water. That's not a likely system to occur, or to exist for very long at STP with normal humidity, but hey...nits need to be picked.
What is more dense radon or water?
Radon is a gas, water is a liquid. Under the same conditions radon should be many hundreds of times less dense than water. Water's density at STP is about 1 000 kg/m3. Radon's density at STP is about 9.73g/m3. Thus, water is about 103 times denser than radon.
Is nitrogen a solid at stp?
No. Nitrogen is a gas in atmosphere, the air we breathe.
Which group 15 element exists as diatomic molecules at STP?
nitrogen
Which 2 elements are gases at STP?
hydrogen, nitrogen, oxygen, fluorine, and chlorine are all gases at STP
What is the speed of STP cable?
10 to 1000 Mbps for less than +/- 100m
When an object or liquid's density is greater than one it wiLL BE WHAT?
The answer will depend on the units used. A density of 1 gram per litre is pretty light (less than the density of air at STP) whereas a density of 1 kilogram per ml is seriously dense.
Why does HE have a molar volume of 22.4dm3 at stp and ch3cl have a molar volume of 21.9dm3 at stp?
Because at STP, Chloroform is liquid and Helium is in gaseous state. When something is in a gaseous state, it occupies a larger space than the liquid. I thought however, that chloroform would occupy less than that
Is mineral water heavier or lighter than distilled water at STP?
Mineral water will be more dense than distilled water. The disolved material adds mass, but does not increase the volume.
Which 5 L cylinder at STP will contain the greatest mass of gas particles nitrogen or neon?
Neon, as its mass is 20.18 and Nitrogen's is 14.01
