What is the difference of percent of mass and percent of volume?
Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
If you have a tank that holds volume capacity of thirty gallons how do you convert that to find the volume capacity of helium?
Thirty gallons of anything is thirty gallons. Maybe you're asking about compressing helium, but you need to say what pressure you're using and what temperature, to determine how much helium will fit into a 30 gallon tank.
What is the total volume if 5 percent is 460000?
9,200,000 is the total volume.
By what percent does the volume of a cube increase when the length of each of its sides is tripled?
Original volume = (S)3 New volume = (3S)3 = 27(S)3 = 27 times the original volume. The change is (27 times) - (1 time) = 26 times = 2,600 percent Semantic note: After increasing by 2,600 percent, the volume becomes 2,700 percent of what it was originally.
Explain how you can find the volume of helium gas in a one liter tank?
You don't have to find the volume ! If gas is put into a closed container, it fills it. The volume of gas in a one liter tank is one liter.
What is the volume of 10.9 mol of helium at STP?
The volume of 10.9 mol of helium at STP is 50 litres.
Does helium has volume?
yes i does
What percent of hydrogen is fused to helium in the sun and what percent is fused to energy?
99.993 % into Helium, .007 % into energy.
Is helium dence?
depends on the size of its container and volume of helium filling it
When a helium balloon rises in the air it expands. If the volume of the balloon doubles what happens to the density of the helium inside it?
If the volume of the helium balloon doubles as it rises, the density of the helium inside it decreases. This is because the same amount of helium gas is now spread out over a larger volume, leading to a lower density.
Would a balloon float longer if it had 100 percent helium or half helium and half oxygen?
100% helium
What is Jupiter's composition in percent?
Jupiter's composition is primarily hydrogen (about 75%) and helium (about 24%). The rest of its composition consists of trace elements such as methane, ammonia, water, and other compounds.
What will be the volume of 1g of helium at ntp in liters?
At NTP (standard temperature and pressure), which is 0 degrees Celsius and 1 atm pressure, the volume occupied by 1 gram of helium would be approximately 22.4 liters. This value is based on the ideal gas law and the molar mass of helium.
When a helium balloon rises in the air it expands If the volume of the balloon doubles what happens to the density of the helium inside it?
If the volume of the balloon doubles while the mass of helium remains the same, the density of helium inside the balloon would decrease by half. Density is calculated as mass divided by volume, so if volume doubles and mass stays the same, the density will decrease.
What is the percent of helium in the air?
The percentage of helium in Earth's atmosphere is very low, around 0.0005%. Most helium on Earth is found in natural gas deposits underground and is extracted through specialized processes, as it is not a significant component of the air we breathe.
What percent of the Neptunian atmosphere is helium?
Planet Neptune's atmosphere comprises approximately 19% helium (±3.2%).
What is the volume of 84.6 grams of helium at stp?
The volume of any gas at STP (standard temperature and pressure) is 22.4 L/mol. The molar mass of helium is 4.0026 g/mol. So, 84.6 grams of helium would be 84.6/4.0026 = 21.1 mol. Therefore, the volume of 84.6 grams of helium at STP would be 21.1 mol * 22.4 L/mol = 472.64 L.
