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 many molecules are in 100g of H20?
To find the number of molecules in 100 grams of water (H₂O), first calculate the number of moles. The molar mass of water is approximately 18 g/mol, so 100 g of water is about 5.56 moles (100 g ÷ 18 g/mol). Since one mole contains Avogadro's number of molecules (approximately (6.022 \times 10^{23})), the total number of molecules in 100 g of H₂O is approximately (3.34 \times 10^{24}) molecules (5.56 moles × (6.022 \times 10^{23}) molecules/mole).
How many molecules are in 26.3 g of calcium hydroxide?
26.3 g of calcium hydroxide contain 2,054 molecules.
How many molecules of water are there in 1.802 grams of water?
To calculate the number of water molecules in 1.802 grams, first find the molar mass of water (H2O = 18.015 g/mol). Then, divide the given mass by the molar mass to get the number of moles (1.802 g / 18.015 g/mol = 0.1 mol). Finally, multiply the number of moles by Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of water molecules (0.1 mol * 6.022 x 10^23 molecules/mol = 6.022 x 10^22 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 in 1 g of water?
3.345*10^23
Which 1 has more molecules 9 g of water or 9 g of sugar?

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 H2O are in 54.3 g H2O?
To find the number of molecules in 54.3 g of water (H2O), you first need to convert the mass of water to moles using the molar mass of water (18.015 g/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. The calculation would be: 54.3 g / 18.015 g/mol = 3.013 moles, then, 3.013 moles * 6.022 x 10^23 molecules/mol = 1.816 x 10^24 molecules of H2O in 54.3 g 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 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 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 much water in grams can be made from 1.95 and times 1024 hydrogen molecules Answer in units of g.?
The molar mass of water is 18.015 g/mol. So, 1.95 x 10^24 hydrogen molecules would yield 1.95 x 10^24 water molecules. This corresponds to 1.95 x 10^24 x 18.015 g of water, which is approximately equal to 3.51 x 10^25 g of water.
