How many moles are contained in 16.8 L of Xe gas at STP?
16,8 L of Xe gas at STP is equivalent to 0,754 moles.
How many grams of oxygen gas is contained in 11.2L 02 gas at stp?
To determine how many atoms are present in 56 liters of oxygen gas at STP you first need to know that there are two atoms in a single molecule. Then, you would work the scientific formula to determine the number of molecules in the oxygen gas.
How many grams of methane gas CH4 are contained in a volume of 144 liters at STP?
One mole has amass of 16g.There are 6.428mol.Its mass is 102.85g
How many oxygen molecules are present in 113.97 liters of oxygen gas at STP?
At STP, one mole of any gas occupies 22.4 liters. This is called molar volume. 113.97 liters ÷ (22.4 L/mol) = 5.09 moles Then convert moles to molecules (1 mole = 6.02 × 1023 molecules) 5.09 moles × (6.02 × 1023 molecules/mol) = 3.06 × 1024 molecules
HOW many grams pf ammonia are in 387x1021 molecules?
Assuming that this ammonia gas is at STP, you can use Avogadro's number to gind the number of moles of gas:(387 x 1021 molecules) x (1 mol / 6.02x1023particles) x (17.03 g / 1 mol) =110 g NH3
How many molecules are in 30 liters of methane (CH4) at STP?
How many molecules are in 30 liters of methane (CH4) at STP
How many liters are in 5.4x1024 molecules of nitric oxide at STP?
The volume is 19,48 L.
How many hydrogen molecules are in 31.8 L H2(g) at STP?
The answer is 8,5379.10e23 molecules.
How many moles are contained in 16.8 L of Xe gas at STP?
16,8 L of Xe gas at STP is equivalent to 0,754 moles.
How many grams of oxygen gas is contained in 11.2L 02 gas at stp?
To determine how many atoms are present in 56 liters of oxygen gas at STP you first need to know that there are two atoms in a single molecule. Then, you would work the scientific formula to determine the number of molecules in the oxygen gas.
How many molecules of SO2 gas would occupy 4.15 L at STP?
1.12 X10 to the 23rd power molecules SO2
How many butane molecules are in 22.4 liters of C4H10 gas at STP?
6.023 x 1023
How many molecules of calcium carbonate are present in its one mole?
If its at STP (standard temperature & pressure) then i think 6 x 10^23 molecules
Why is nitrogen gas at STP less dense than Xe gas at STP?
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.
How many molecules of ethane are present in 64.28 liters of ethane gas (C2H6) at STP?
at STP 1 mole occupies 22.4 litres. 64.28 / 22.4 is 2.8696428 moles. Multiply this by avagadro's constant (6.022*10^23) gives 1.7281x10^24 molecules
How many moles of o2 molecules are there in 50dm3 of o2 gas at STP?
A cubic decimeter is a liter, so we're talking 50L of oxygen gas at STP. 1mol of any gas at STP occupies 22.4L of space, so 50/22.4 = about 2.2mol of oxygen.
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
