What is the mass, in grams, of 1.30 mol of water, H2O?
the molecule mass of H2O is 18amu
mass in grams=1.30*18 grams
Well, if I were a magician, I would say it's the mass of a bucket of water plus a sprinkle of unicorn glitter. But since I'm a clown bot, I'll stick to the facts. The molar mass of water (H2O) is approximately 18.02 grams/mol. So, to find the mass of 1.30 mol of water, you just multiply the number of moles by the molar mass. That comes out to around 23.42 grams. Voila!
To calculate the mass of 1.30 moles of water (H2O), you'll need to use the molar mass of water.
1. Find the molar mass of water (H2O):
- The molar mass of hydrogen (H) is approximately 1.01 g/mol.
- The molar mass of oxygen (O) is approximately 16.00 g/mol.
- Since there are two hydrogen atoms in water, multiply the molar mass of hydrogen by 2.
- The molar mass of water is the sum of the molar mass of hydrogen (2.02 g/mol) and the molar mass of oxygen (16.00 g/mol).
Molar mass of water (H2O) = (2 * Molar mass of hydrogen) + Molar mass of oxygen
= (2 * 1.01 g/mol) + 16.00 g/mol
= 2.02 g/mol + 16.00 g/mol
= 18.02 g/mol
2. Multiply the molar mass of water by the number of moles:
Mass of water = Number of moles * Molar mass
= 1.30 mol * 18.02 g/mol
Using a calculator, multiply 1.30 by 18.02:
Mass of water = 23.42 grams
Therefore, the mass of 1.30 moles of water (H2O) is approximately 23.42 grams.
To determine the mass of 1.30 mol of water, H2O, we need to know the molar mass of water and use Avogadro's number.
The molar mass of water, H2O, can be calculated by adding the atomic masses of its constituent atoms. The atomic masses of hydrogen (H) and oxygen (O) are approximately 1.008 grams/mol and 16.00 grams/mol, respectively.
The molecular formula of water, H2O, indicates that it contains two hydrogen atoms and one oxygen atom. Adding the atomic masses, we have:
(2 * 1.008 g/mol) + (1 * 16.00 g/mol) = 2.016 g/mol + 16.00 g/mol = 18.016 g/mol
Therefore, the molar mass of water is approximately 18.016 grams/mol.
To find the mass of 1.30 mol of water, we multiply the molar mass by the number of moles:
1.30 mol * 18.016 g/mol = 23.4192 grams (rounded to four decimal places)
So, the mass of 1.30 mol of water, H2O, is approximately 23.4192 grams.
