Formula mass / Formula weight / Molecular mass / Molecular weight of H2O = (1*2) + 16 = 18g
1 mol of H2O = 18g H2O
1 mol of H2O = 6.023 * 10^23 molecules
In 18g H2O there are 6.023 * 10^23 molecules.
So,
In 1g H2O there are (6.023 * 10^23) / 18 molecules = 3.346 * 10^22 molecules
Therefore,
In 7.3g H2O there are (3.346 * 10^22) * 7.3 molecules = 2.443 * 10^23 molecules
Ans: 2.443 * 10^23 molecules

How many molecules of H2O are there in 1.0 g of H2O?
There are 3.34 x 10^22 molecules of H2O in 1.0 g of water.
How many molecules of H2O are in 0.943 moles of H2O?
0.943 moles H2O (6.022 X 1023/1 mole H2O) = 5.68 X 1023 molecules of water ========================
How many molecules are there in two moles of water?
There are 1.204 x 10^24 water molecules in two moles of water. This is because one mole of anything contains Avogadro's number of particles, which is 6.022 x 10^23. Thus, two moles of water would have twice that number of molecules.
How many H2O molecules are in the ocean?
There are approximately 1.332×10^24 water molecules in the ocean.
How many molecules are in 4.21 grams of water?
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
How many molecules of H2O are there in 1.0 g of H2O?

There is one water molecule in H2O
How many mg are in 72g?
72,000 mg
How many molecules of H2O are in 0.583 mol of H2O?
There are 3.505 x 10^23 molecules of H2O in 0.583 mol of H2O, because 1 mol of any substance contains 6.022 x 10^23 molecules.
How many molecules of H2O are in 0.943 moles of H2O?
0.943 moles H2O (6.022 X 1023/1 mole H2O) = 5.68 X 1023 molecules of water ========================
How many molecules of H2O equals 1 mole of H2O?
the rule for solving amount of molecules is N(molecules)=6x10^23 x n(amount of mole) therefore there are 6x10^23 molecules in 1 mole of anything or in this case of H20
How many H2O molecules are contained in 1 mole?
Because they are.
How many molecules are there in two moles of water?
There are 1.204 x 10^24 water molecules in two moles of water. This is because one mole of anything contains Avogadro's number of particles, which is 6.022 x 10^23. Thus, two moles of water would have twice that number of molecules.
How many H2O molecules are in the ocean?

How many H2O molecules produced in Krebs cycle?
During the Krebs cycle, one molecule of water (H2O) is produced for each round of the cycle. At the end of the cycle, a total of two molecules of water per molecule of glucose are generated.
How many oxygen atoms are in 12 h2o?
There is 1 O atom in 1 H2O molecule thus there are 12 O atoms in 12 H2O molecules.
How many molecules are in 4.21 grams of water?
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
