How do I convert the following quantity to moles?
44.0g of H2O
divide 44 by the mole mass of H2O. Mole mass of H2O is 2*1+16=18. You need to do it accurately.
Thank you soo much! :)
To convert grams to moles, you need to use the molar mass of the substance.
1. First, find the molar mass of H2O, which is the sum of the molar masses of hydrogen (H) and oxygen (O).
The molar mass of hydrogen (H) is approximately 1.01 g/mol, and the molar mass of oxygen (O) is approximately 16.00 g/mol.
So, the molar mass of H2O is approximately 2*(1.01 g/mol) + 16.00 g/mol = 18.02 g/mol.
2. Use the molar mass to convert grams to moles.
Divide the given mass of 44.0 g by the molar mass of H2O:
44.0 g / 18.02 g/mol = 2.44 mol.
Therefore, 44.0 g of H2O is approximately equal to 2.44 moles.
To convert the quantity of a substance to moles, you need to use the molar mass of the substance.
1. First, you need to determine the molar mass of H2O.
- H2O has two hydrogen atoms and one oxygen atom.
- The atomic mass of hydrogen (H) is approximately 1 gram per mole (g/mol).
- The atomic mass of oxygen (O) is approximately 16 g/mol.
- Adding the atomic masses of the atoms in H2O gives us:
Molar mass of H2O = (2 * atomic mass of hydrogen) + atomic mass of oxygen
= (2 * 1 g/mol) + 16 g/mol
= 18 g/mol
2. Now, use the molar mass of H2O to convert grams to moles.
- Divide the given mass of H2O (44.0 g) by the molar mass of H2O (18 g/mol):
Moles of H2O = Mass of H2O / Molar mass of H2O
= 44.0 g / 18 g/mol
= 2.44 moles (rounded to two decimal places)
Therefore, 44.0 grams of H2O is equivalent to 2.44 moles of H2O.
