Which 1 has more molecules 9 g of water or 9 g of sugar?
9g of water
How many molecules are in 6.9 g H2O?
To determine the number of molecules in 6.9 g of water (H2O), you first need to convert grams to moles. The molar mass of water is approximately 18 g/mol. Therefore, 6.9 g is equal to 6.9/18 = 0.383 moles of water. Next, you can use Avogadro's number (6.022 x 10^23) to find the number of molecules in 0.383 moles of water, which is approximately 2.3 x 10^23 molecules.
How many molecules are there in 95.2 g of water?
To find the number of molecules in 95.2 g of water, first calculate the number of moles using the molar mass of water (18.015 g/mol). Next, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. So, (95.2 , \text{g} \times \frac{1 , \text{mol}}{18.015 , \text{g}} \times 6.022 \times 10^{23} , \text{molecules/mol}) gives you the number of molecules.
How many molecules of water is present in 10 ml of water?
Assuming a density of 1.0 g/ml for water, then 10 ml H2O = 10 g10 g H2O x 1 mol/18 g = 0.5555 moles H2O0.5555 moles x 6.02x10^23 molecules/mole = 3.34x10^23 molecules of H2O in 10 ml
How many molecules of H2O are there in 1.0 g of H2O?
There are 3.34 x 10^22 molecules of H2O in 1.0 g of water.
How many molecules of oxygen are produced when a sample of 29.2 g of water is decomposed by electrolysis?
The molar mass of water is 18 g/mol, so 29.2 g is equivalent to 1.62 mol of water. Through electrolysis, each water molecule decomposes into 1 molecule of oxygen and 2 molecules of hydrogen. Therefore, 1.62 mol of water will produce 1.62 mol of oxygen molecules, which is equivalent to 9.73 x 10^23 molecules of oxygen.
How many moles of water molecules h2o are present in a 27 rams sample of water?
To find the number of moles of water molecules in a 27 gram sample, you need to divide the mass by the molar mass of water (18.015 g/mol). 27 g / 18.015 g/mol = approximately 1.5 moles of water molecules.
How many molecules are in 32 g of SO2?
32 g SO2 x 1 mole SO2/96 g x 6.02x10^23 molecules/mole = 2.0x10^23 molecules
How many molecules are in 12.5g of water?
The molar mass of water (H2O) is approximately 18 g/mol. To calculate the number of molecules in 12.5 g of water, we need to convert grams to moles by dividing by the molar mass. 12.5 g / 18 g/mol = 0.694 moles. Since 1 mole of any substance contains 6.022 x 10^23 molecules (Avogadro's number), multiplying 0.694 moles by Avogadro's number gives us approximately 4.18 x 10^23 molecules of water in 12.5 g.
How do I calculate the quantity of oxygen that contains same number of molecules as 36 grams of water?
36 g water contain 32 g oxygen.32 g oxygen is equivalent to 1 mol oxygen.1 mol has 6,023.10e23 molecules (or atoms, ions).
How many molecules are present in 17.0 moll of water?
To find this out you simply times 17 by avogadros number 17mol H2O X 6.022x10^23 molecules of anything/mol of anything mols cancel and you are left in molecules of H2O the answer is 1.024x10^25 molecules H2O
How many hydrogen atom present in 1 picolitre of water?
To find no; of atoms of hydrogen, we need to find the no; of water molecules in 1 pL of water. Density of water = mass/volume = 1 g/cc mass of 1pL of water = density * volume = 1 g/cc * 10-9 cc (1L = 103 cc, so 10-12 L = 10-9 cc) = 10-9 g 18g of H2O = 6.023 * 1023 molecules. hence, 10-9 g of H2O = 3.346 * 1013 molecules of H2O 1 molecule of H2O = 2 atoms of H hence 1pL = 6.692* 1013 atoms of H
