For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the Atomic Mass. Multiply by one mole for units to cancel. H2O=18.0 grams
235 grams H2O / (18.0 grams) = 13.1 moles H2O
1 mole is equal to 18 grams of H2O, so 60 grams is 3.33 moles.
In 1 mole of water (H2O), there are 2 moles of hydrogen (H). This means that in 2.08 moles of water, there are 2.08 x 2 = 4.16 moles of hydrogen. To convert moles to grams, we use the molar mass of hydrogen: 4.16 moles x 1.01 g/mol = 4.22 grams of hydrogen.
First you find the Molar Mass of water using the values on the periodic table.2 Hydrogen + 1 Oxygen2*1.01 + 16.00 = 18.02 g/molThen using factor-label to cancel out units(100g H2O)*(1 mol H2O / 18.02 g H2O) = 5.54938957 molSo the number of moles in 100g of H2O is about 5.55 moles.Hope that helps.
For this you need the atomic (molecular) mass of H2O. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. H2O= 18.0 grams2.5 moles H2O × (18.0 grams) = 45.0 grams H2O
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
The answer is 0,44 moles.
1 mole is equal to 18 grams of H2O, so 60 grams is 3.33 moles.
53 grams ÷ 18.01 grams/mole = 2.94 moles
To find the mass of 1.54 moles of H2O, you can use the molar mass of water. The molar mass of H2O is 18.015 grams/mol. Therefore, the mass of 1.54 moles of H2O would be 1.54 moles * 18.015 grams/mol = approximately 27.75 grams.
Two moles of water are produced.
In 1 mole of water (H2O), there are 2 moles of hydrogen (H). This means that in 2.08 moles of water, there are 2.08 x 2 = 4.16 moles of hydrogen. To convert moles to grams, we use the molar mass of hydrogen: 4.16 moles x 1.01 g/mol = 4.22 grams of hydrogen.
To calculate the number of grams in 2.50 moles of H2O, you first need to know the molar mass of water (H2O), which is approximately 18.015 g/mol. Then, you can use the formula: grams = moles x molar mass. So, 2.50 moles of H2O is equivalent to 45.04 grams (2.50 moles x 18.015 g/mol).
1 mole H2O = 18.015g H2O 1.57mol H2O x 18.015g H2O/1mol H2O = 28.3g H2O
To teach you how to do this problem: 1. Look at the Periodic Table. O =16 grams/mole, H =1.01 grams/mole 2. Calculate the Molecular Weight of Water. 1*O + 2*H: 16+2.02=18.02g/mole 3. Divide the mass of what you have by the Molecular Weight: 35.1g H2O/(18.02 g H2O/mole H2O) 4. The units g H2O cancel leaving you with mole H2O. 5. 35.1 grams H2O= 1.95 moles H2O
For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. H2O= 18.0 grams500.0 grams H2O / (18.0 grams) = 27.8 moles H2O
3.65 grams of water is equal to .203 moles of H2O. This means there is also .203 moles of H2 present, or .408 grams.
Since the molar mass (grams per mole) of H2O is 18.02, the grams of H2O in 4 moles is 72.08g.
