Quick Answer: How many atoms are in 3 moles of h2o?

How many atoms are there in 3 moles of water?

one mole of water contains 6.02 x 1023 MOLECULES of water.

But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

How many atoms are in 3.0 moles h2o?

As hydrogen gas is diatomic, 3 moles of hydrogen gas contains 3 x 6.022 x 10^23 H2 molecules, each containing 2 hydrogen atoms. Therefore, 3 moles of hydrogen gas contains 2 x 3 x 6.022 x 10^23 hydrogen atoms, or 3.6132 x 10^24.

How many molecules are in 3 moles of water molecules?

So, in 3 moles of the substance, there’ll be 3⋅6=18 moles of water molecules. Remember that a mole of molecules contains 6.02⋅1023 molecules. So here, there’ll be a total of 6.02⋅1023⋅18≈1.08⋅1025 water molecules.

How many atoms are in the human body?

Suzanne Bell, an analytical chemist at West Virginia University, estimates that a 150-pound human body contains about 6.5 octillion (that’s 6,500,000,000,000,000,000,000,000,000) atoms. The vast majority of them are hydrogen (humans are almost entirely water, which comprises two hydrogen atoms and an oxygen).

How many atoms are in the universe?

There are between 1078 to 1082atoms in the observable universe. That’s between ten quadrillion vigintillion and one-hundred thousand quadrillion vigintillion atoms.

How many atoms are in 2 moles?

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.

How many atoms are there in 1 mole of oxygen?

Solution — 1 molecule of O2 = 2 oxygen atoms So, 1 mole of O2 = 2 mole oxygen atoms = 2 × 6.022 × 1023 = 12.044 ×1023 oxygen atoms.

How many molecules is 3 moles?

1 Expert Answer

Do 3 moles x (6.022 x 10^23 molecules / 1 mol) to get about 1.8 x 10^24 molecules.

How many molecules are in a mole?

The mole is represented by Avogadro’s number, which is 6.022×1023 atoms or molecules per mol.

How many water molecules are in 5.2 moles water?

There are therefore 6.02 × 1023 water molecules in a mole of water molecules.
