The molar mass of water (H2O) is approximately 18 grams/mol. Therefore, you would need 18 grams of water to weigh out 1 mole of water.
1 mole H2O = 18.015g H2O 1.57mol H2O x 18.015g H2O/1mol H2O = 28.3g H2O
0.25 mole of H2O
Oxygen limits the reaction, so......Balanced equation. 2H2 + O2 -> 2H2O 7.89 mole H2O (1 mole O2/2 mole H2O) = 3.95 mole oxygen gas needed ------------------------------------------
593 g H2O x 1 mol/18 g x 2 mole H/mole H2O x6.02x10^23 H atoms/mole H = 4x10^25 atoms of H
To have 1 mole of H2O, you would need to weigh out approximately 18 grams of water (H2O). This is because 1 mole of water molecules (H2O) has a molar mass of about 18 grams/mol (2 grams/mol for hydrogen x 2 atoms + 16 grams/mol for oxygen).
The molar mass of water is approximately 18.02 g/mol. Therefore, one mole of water would weigh approximately 18.02 grams, considering 4 significant figures.
The molar mass of water (H2O) is approximately 18 grams/mol. Therefore, you would need 18 grams of water to weigh out 1 mole of water.
In 1 mole of water (H2O), there are approximately 6.022 x 10^23 molecules of H2O.

It would be a mole of water because you find the molar mass of each compound, finding water is 18.016 g/mol and methane is 16.042 g/mol. Why? water= H2O H 2 x 1.008 O 1 x 16.000 18.016 g/mol methane= CH4 C 1 x 12.010 H 4 x 1.008 16.042 g/mol
1 mole H2O = 18.015g H2O 1.57mol H2O x 18.015g H2O/1mol H2O = 28.3g H2O
Since 1 molecule of H2O contains 2 atoms of hydrogen, 11.5 mol of H2O contains 11.5 mol x 2 = 23 mol of hydrogen atoms.
In the reaction provided, the balanced equation is: CaCO3 + 2 HCl -> CaCl2 + CO2 + H2O. One mole of CaCO3 reacts with 2 moles of HCl to produce 1 mole of H2O.
0.25 mole of H2O
No, a mole of water (H2O) and a mole of sugar (C12H22O11) both contain Avogadro's number of molecules, which is approximately 6.022 x 10^23. Therefore, they have the same number of particles and weigh the same, which is about 18 grams for water and about 342 grams for sugar.
0.87 grams water (1 mole H2O/18.016 grams)(1 mole O/1 mole H2O)(6.022 X 1023/1 mole O) = 2.9 X 1022 atoms of oxygen --------------------------------------
