How many moles are in 8g of H2O?
To calculate the number of moles in 8g of H2O, we must first calculate the molar mass of H2O (18.015 g/mol). Then, we can use the formula moles = mass / molar mass to find that there are approximately 0.444 moles of H2O in 8g.
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 moles are in 27.4 g of water?
27.4 g H2O x 1 mole/18 g = 1.52 moles
How many molecules are in 2.81g H2O?
To calculate the number of molecules in 2.81g of H2O, you first need to convert grams 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: 2.81g H2O / 18.015 g/mol = 0.156 moles H2O; 0.156 moles H2O x 6.022 x 10^23 molecules/mol = 9.40 x 10^22 molecules of H2O.
What is the mass of 2.1 moles H2O?
The molar mass of water (H2O) is approximately 18.015 g/mol. Therefore, the mass of 2.1 moles of H2O would be approximately 37.83 grams.
How many gram are in 3.0 moles of H2O?
3.0 moles of H2O have 54 g.
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

What is the mass of 2.1 moles H2O?
The molar mass of water (H2O) is approximately 18.015 g/mol. Therefore, the mass of 2.1 moles of H2O would be approximately 37.83 grams.
How many moles of water does 6.00 g of water contain?
6.00 g H2O x 1 mol H2O/18 g H2O = 0.333 moles of water present in 6.00 g of water. How anyone came up with 3.00 moles is a mystery.
How many moles of H2O can be formed when 4.5 moles of NH3 react with 3.2 moles of O2 NH3 plus O2 yields NO plus H2O?
Using the molar mass of nh3, we find that we have 2.5 moles of nh3. Since 3 moles of h2o are produced per 2 moles of nh3, we see that we will produce 3.75 moles of h2o. This is equivalent to around 3.79 g.
How many moles are in 117g of H2O?
To find the number of moles in 117g of H2O, you first need to determine the molar mass of H2O, which is approximately 18 g/mol. Then, divide the mass given (117g) by the molar mass to find the number of moles. In this case, 117g of H2O is equal to 6.5 moles.
How many moles of water are on 72.08g of H2O?
To determine the number of moles of water in 72.08g of H2O, we first need to calculate the molar mass of water (H2O). The molar mass of water is approximately 18.015 g/mol (2 hydrogen atoms with a molar mass of 1.008 g/mol each, and 1 oxygen atom with a molar mass of 16.00 g/mol). Next, we use the formula: moles = mass / molar mass. Plugging in the values, we get moles = 72.08g / 18.015 g/mol ≈ 4 moles of water. Therefore, there are approximately 4 moles of water in 72.08g of H2O.
How much does 10 moles of water weigh?
As the molar mass of water is 18 g/mol (1*2 H + 16 O) 10 moles*18 g/mole=180 grams.
