What sample at STP has the same number of molecules as 5 liters of NO2 at STP?
At STP, 1 mole of any ideal gas occupies 22.4 liters. Therefore, 5 liters of NO2 at STP will represent 0.22 moles (5/22.4), and this is the case for any other ideal gas. So, the answer is that 5 liter of ANY ideal gas will have the same number of molecules as 5 liters of NO2.
How many molecules in 38 grams of oxygen gas?
38 grams oxygen gas (1 mole O2/32 grams)(6.022 X 1023/1 mole O2) = 7.2 X 1023 molecules of oxygen gas -------------------------------------------------
The number of molecules in 48.0 grams of oxygen gas (O2) is?
48.0 g O2 x 1 mole O2/32 g x 6.02x10^23 molecules O2/mole O2 = 9.03x10^23 molecules of O2
How many molecules are there in 18.9 moles of chlorine gas?
One mole is 6.022 × 1023 (or 602,200,000,000,000,000,000,000) bits of anything. You have 18.9 moles. Thus: 18.9 × (6.022 × 1023) = 1.138158 × 1025 (or 11,381,580,000,000,000,000,000,000) molecules Cl2.
Why does 10g of nitrogen gas contain the same number of molecules as 10g of carbon molecules?
No, they do NOT contain the same number of particles (either molecules N2 or atoms C): there molecular or atomic mass is different.Look at this:10g N2 / 28 (g/mole N2) x 6.022x1023 (molecules N2/mole N2) = 2.15 x1023 molecules N210g C / 12 (g/mole C) x 6.022x1023 (atoms C/mole C) = 5.02 x1023 atoms C
In 1 mole of NO2 gas how many protons are there?
N has 7 protons O has 8 protons (O2 therefore 16) So 1 molecule of NO2 gas has 7 + 16 = 23 protons 1 mole of NO2 gas (6.022 * 1023 molecules) have 138.506 * 1023 protons.
What sample at STP has the same number of molecules as 5 liters of NO2 at STP?
At STP, 1 mole of any ideal gas occupies 22.4 liters. Therefore, 5 liters of NO2 at STP will represent 0.22 moles (5/22.4), and this is the case for any other ideal gas. So, the answer is that 5 liter of ANY ideal gas will have the same number of molecules as 5 liters of NO2.
How many atoms of sodium are in 0.250 moles of Na2SO4?
in 0.25 moles there are 1.505*10^23 molecules (1 mole of any element=6.023*10^23 molecules)
What ia a mole of gas?
A mole of gas is equal to 6.02 x 1023 gas molecules.
A gas contains NO2 molecules at 44C What is the average speed of the molecules and the mass of a NO2 molecule is 7 point 64 times 10 to the negative 26 kg?
ABigNumber.
How many molecules in 38 grams of oxygen gas?
38 grams oxygen gas (1 mole O2/32 grams)(6.022 X 1023/1 mole O2) = 7.2 X 1023 molecules of oxygen gas -------------------------------------------------
How many no of molecules are present in one mole of CO2 gas?
One mole is 6.02 × 1023 of anything.One mole of atoms is 6.02 × 1023 atoms, one mole of rice is 6.02 × 1023 grains, one mole of shoes is 6.02 × 1023 shoes. You get the picture?One mole of molecules is 6.02 × 1023molecules.
If 1.oo mole of nitrogen gas is a stp. How many molecules of the gas will fill a 22.4 liter gas chamber?
This number is 6,022 140 857.
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
How many moles of chlorine gas are contain in 9.02x1023 molecules?
Since 1 mole is (6.022×1023 molecules)/(mol), so 9.02 x 1023 molecules would be 1.4978... mol
How many moles of chlorine gas are contained in 9.02 x 1023 molecules?
9.02*1023 (molecules) divided by 6.022*1023 (molecules per mole) = 1.5 moles of ANY thing
What dose no2 stand for?
if you mean NO2, then 1 Nitrogen, 2 Oxygen. It is a toxic brown gas called nitrogen dioxide. if you mean No2, then no such substance exists. No is the element called nobelium. Since it is a metal it does not form molecules.
