How many molecules are in 6 grams of h20?

There are 2.2×1023 molecules in 6.6 g H2O.

How many grams of water are in 1 mole of water?

The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.

How many moles are present in 5 gram of water?

5/18 moles for 5 grams of water.

How many moles are 3.6 of water?

Hence, the number of moles present in 3.6 gram of water are 0.2 moles.

How many atoms are in 6.5 moles of zinc?

The Mole 1) How many zinc (Zn) atoms in 5.16 moles of Zn? Atom = Mole / 6.0221415E+23. 6.5 moles 6.02 x 1023 atoms = 3.9 x 1024 atoms 1 mole 2.

How many moles of hydrogen are needed for 100 grams of water?

Unlock

1 mole of water requires 1 mole of hydrogen (H2) and 0.5 moles of oxygen (O2). This requires 100/18 moles of hydrogen. As the molar mass of hydrogen is 2, it requires 200/18 = 100/9 g of hydrogen. It requires 100/9 g of hydrogen gas and 800/9 g of oxygen gas to make 100 g of water.

How many grams are in 2 moles of water?

It is equal to Avogadro’s number (NA), namely 6.022 x1023. If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.

How many moles are 5.4 gram of water?

5.4 grams H20 * (1 mole H2O / 18 grams H2O) gives the number of moles of water. Call this X. Note that units come out to “moles H2O”. X moles H2O * (6.02*10^23 molecules H2O / mole H2O) is your answer.
