The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17
The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18
This means that one mole of NH3 weigh less than one mole of H2O
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).
1 mole H2O = 18.02g --- water is H2O ... 2 x 1.008 + 1 x 15.996 = 18.012 g/mole = 18.01 grams
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.
36g
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.
Molar ratio's in this balanced equation: 1 + 2 --> 1 + 1 + 1 (H2O) respectively
0.25 mole of H2O
A mol is a mol is a mol - no. A mol is a standard unit of measurement and thus any substance, when designated a "mol" will have the same number of particles. Therefore, a mol of salt would have the same number of particles as a mol of sugar. It is like asking if a pound of feathers would weigh more or less than a pound of steel.
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 --------------------------------------
