What is the density of helium?
0.164 g/l.
Helium, which has a mass of 4.00 g/mol, has a density of 0.164 g/l.
What is the density of ammonia gas?
0.73 kg/m³
Ammonia/Density
How do you find the density of ammonia?
Now the density can be calculated by dividing the mass of one mole of ammonia by the volume above. As a point of comparison, this density is slightly less than the density of ammonia at STP, which is equal to (170.4g/mol)(22.4L/mol)=0.761g/L.
What is the color for helium?
colorless
| Helium | |
|---|---|
| Pronunciation | /ˈhiːliəm/ (HEE-lee-əm) |
| Appearance | colorless gas, exhibiting a gray, cloudy glow (or reddish-orange if an especially high voltage is used) when placed in an electric field |
| Standard atomic weight Ar, std(He) | 4.002602(2) |
| Helium in the periodic table |
Is ammonia more dense or less dense than air?
Anhydrous ammonia gas is lighter than air and will rise, so that generally it dissipates and does not settle in low-lying areas. However, in the presence of moisture (such as high relative humidity), the liquefied anhydrous ammonia gas forms vapors that are heavier than air.
How much helium does it take to lift 1 kg?
Re: How much helium do one need to lift 1Kg You need about 700g of helium to generate 1kg lift (assuming the helium is at the same temperature and pressure as the surrounding air).
How do you calculate ammonia volume?
-Use the formula: volume of ammonia gas = number of moles × volume at STP.
How many shells are in helium?
one
Helium only has one atomic shell, which fills up when it has two electrons.
What are 3 interesting facts about helium?
Ten Facts about Helium
- Helium is the second most abundant element in the universe, and the second lightest element.
- It is estimated that our sun produces 700 million tons of helium per second.
- Helium has the lowest boiling point of all elements—4.2 degrees Kelvin (that -268.8 Celsius)—just 4 degrees above absolute zero.
How is the density and specific weight of helium determined?
