3 moles of Oxygen atoms weigh
48.00 grams
.
How many atoms are in 3 moles of O2?
Explanation: 1 mole of a substance there are 6.022*10^23 atoms/molecules. From this we can deduce that there are
3*6.022*10^23 O2 molecules
in 3 moles.
What is the mass of a mole of oxygen gas?
A mole of oxygen atoms
16 grams
while a mole of oxygen molecules is 32 grams.
What is the mass of 2 oxygen moles?
per mole of oxygen. From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is
63.9976 g
..
What is the mass of 4.00 moles of oxygen gas?
4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole =
128 g
. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.
How do you find moles of oxygen gas?
To calculate the molar mass of oxygen gas, we simply
multiply the molar mass of oxygen by two
. This gives us a molar mass of 32 grams per mole. We can then substitute the mass and molar mass into the key equation. We perform the calculation and determine the number of moles of oxygen gas to be seven moles.
How many molecules is 3 moles?
1 Expert Answer
Do 3 moles x (6.022 x 10^23 molecules / 1 mol) to get about

4) How many grams do 3.294 x 1021 molecules of FeSO4 mass?
What is K mole?
39.10 grams
is the molar mass of one mole of K.
How many particles are in 2 moles of oxygen?
So, 2moles of O2 contains 2× 6.023×10^23 molecule=
12.046 ×10^23 molecule
.
What will be the mass of 2 moles of water?
One mole of H2O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol =
2 g/mol
.
How many moles are in oxygen?
There are
2 moles
of oxygen molecules; there are 4 moles of oxygen atoms.
What is the mass of 2.5 moles of oxygen?
Mass of 2.5 g atoms of oxygen = 16 x 2.5 =
40 g
.
What is the mass of 10 moles of oxygen?
mass =
320 grams
….
How many grams of oxygen is liberated by the electrolysis of water?
how many grams of oxygen is liberated by the electrolysis of water after passing 0.565A for 185 seconds? 4 electrons are involved in liberation of 1 mol
(32.00 g)
of oxygen.
What is the mass in grams of 1.00 moles of oxygen gas?
Moles of a Substance and the Molecular Weight
The mass of oxygen equal to one mole of oxygen is
15.998 grams
and the mass of one mole of hydrogen is 1.008 g. If we total up the gram amounts of each element in the water molecule = 15.998g/mol + 2(1.008g/mol) we get the molar mass of water = 18.014g/mol.
