How many moles of oxygen gas are there in 180 L of oxygen at STP?
If the density of oxygen atSTP is 1,429 g/L the mass of 180 L is 257,22 g.If the mole of oxygen (O2) is 15,999 g the number of moles is 16,077.
How many grams of oxygen gas is contained in 11.2L 02 gas at stp?
At STP (Standard Temperature and Pressure), 1 mole of any ideal gas occupies 22.4 liters. Since 11.2 liters represent half the volume of a mole, we have 0.5 moles of O2 gas. Using the molar mass of oxygen (O2), which is around 32 g/mol, we find that 0.5 moles of O2 gas would be equivalent to approximately 16 grams.
What is the molar mass of a gas if 1.10g of the gas has a volume of 245mL at STP?
48. Assuming we can use the ideal gas law PV=nRT, we can see that if pressure and temperature are fixed, a gas will assume a volume proportional to the number of moles of that gas present (R is a constant). Oxygen gas (O2) has a molecular mass of 32, so 1 mole of oxygen has a mass of 32g in that volume, whereas your gas has a mass of 48g (as the volume is fixed, multiply the mass by the density difference) so the molecular weight of your gas is 48 - possibly ozone (O3).
What is the mass of 39.6 dm3 of argon gas collected at STP?
The molar volume of any ideal gas at standard temperature and pressure (STP) is 22.4 L/mol. Converting 39.6 dm3 to liters gives 39.6 L. To find the mass of argon gas, we calculate the number of moles using the ideal gas equation (PV = nRT) and then multiply by the molar mass of argon.
What is the mass of 0.2 moles of oxygen gas?
The mass of 0,2 moles of oxygen gas is 6,4 g.
What type of element of oxygen?
A gas at STP.
Oxygen is what type of element?
part of the oxygen group....gas, nonmetal...
How many moles are in 68.5 liters of oxygen gas at STP?
1 mole of any gas occupies 22.4 liters at standard temperature and pressure (STP). Therefore, 68.5 liters of oxygen gas at STP would be 68.5/22.4 = 3.06 moles of oxygen gas.
How many moles of oxygen in 10dm3?
No. of moles = mass/relitive molecular mass in this case = 10/16 = 0.625 so that's 0.625 of a mole and a mole of anything contains 6.022 x 1023 atoms = 3.76 x 1023 atoms in 10g of oxygen.
How many liters of oxygen gas are present in 11.3 grams of oxygen gas?
Because oxygen gas (O2) has a molar mass of 32g/mol, 11.3 g * 1/32 mol/g gives about .35 moles. An ideal gas has a volume of 22.4 L/mol at STP, so 11.3 g O2 would have a volume of 7.91 L at STP.
What is the mass of 43.7 L of helium at STP?
The mass of 43,7 L of helium at STP is 7.8 g.
One mole of oxygen gas at stp occupies 22.4 what?
One mole of any gas at STP occupies 22.4 liters. Therefore, one mole of oxygen gas at STP also occupies 22.4 liters.
Why is nitrogen gas at STP less dense than Xe gas at STP?
Nitrogen gas at STP is less dense than xenon gas at STP because nitrogen has a lower atomic mass and thus lighter molecules, leading to lower density. Additionally, xenon is a noble gas with a higher atomic mass and larger atomic radius, contributing to its higher density.
How many moles of oxygen gas are there in 180 L of oxygen at STP?
If the density of oxygen atSTP is 1,429 g/L the mass of 180 L is 257,22 g.If the mole of oxygen (O2) is 15,999 g the number of moles is 16,077.
What is the mass of ethane gas inside a 5.00 L vessel at STP?
The molar volume of a gas at STP (Standard Temperature and Pressure) is 22.4 L. Ethane gas has a molar mass of 30.07 g/mol. Therefore, the mass of ethane gas in a 5.00 L vessel at STP can be calculated as (5.00 L / 22.4 L) * 30.07 g/mol.
In what phase would a substance with a volume of 25.00mL and a mass of 78.05g be at STP?
Gas
What is the state of matter of oxygen?
Oxygen is typically found in the gaseous state at room temperature and pressure.
