1 mole of water is equal to 18.02 grams.
H = 2 * 1.01 g = 2.02 g
O = 1 * 16.00 g = 16.00 g
Total = 18.02 g
1.8 g H2O * (1 mol H2O/18.02 g H2O) = 0.099889 mol H2O
There are about 9.99*10-2 moles in 1.8 grams of water.

To find the number of moles, divide the given mass by the molar mass. So, 1.78g / 18.0g/mol = 0.099 moles of water.

Wiki User
∙ 13y agoThere is 1 mole of water for every 18 grams of water (the atomic mass of oxygen is 16 and the Atomic Mass of hydrogen is 1 gram, so 16 + 1 + 1 = 18).

∙ 10y agoMolecular mass of H2O = 18.0
Amount of H2O = 18/18.0 = 1.0mol
1 mole of water is present in a 18g pure sample.

How many moles of water are in 0.34g of water?
To find the number of moles in 0.34g of water, you first need to calculate the molar mass of water, which is approximately 18g/mol. Then, divide the given mass by the molar mass to get the number of moles. Therefore, 0.34g / 18g/mol ≈ 0.019 moles of water.
How many moles are in 27.8 grams of water?
To find the number of moles in 27.8 grams of water, you would first calculate the molar mass of water (18.015 g/mol). Then, divide the given mass by the molar mass to get the number of moles. In this case, 27.8 grams divided by 18.015 grams/mol is approximately 1.54 moles of water.
What is the mass of water in a 2.5 molar solution of calcium nitrate if the mass of the solute is 8.2grams?
To calculate the mass of water in the solution, you first need to find the molar mass of calcium nitrate (Ca(NO3)2), which is 164.1 g/mol. Next, calculate the moles of solute by dividing the mass of the solute by its molar mass. Then, use the molarity and moles of solute to find the moles of water in the solution using the formula: moles of water = moles of solute * 2 (since calcium nitrate has 2 nitrate ions per formula unit). Finally, find the mass of water by multiplying the moles of water by the molar mass of water (18 g/mol).
How many moles of water were lost if the amount of water lost was 0.293 grams?
To find the number of moles of water lost, we first need to know the molar mass of water, which is approximately 18 g/mol. Then, we can use the formula moles = mass / molar mass to calculate the number of moles lost. In this case, 0.293 grams of water lost would be equivalent to approximately 0.016 moles.
Molar mass of 158g of ice?
The molar mass of ice is 18.015 g/mol. To find the number of moles in 158g of ice, divide the mass by the molar mass: 158g / 18.015 g/mol = 8.77 moles.
How is molar its measured?
In moles of a substance dissolved in 1 L of water.
How many moles are there in 180gm of water?
10 moles of water (molar mass 18.0 g/mol) in 180 g, because 180 /18.0 = 10
Dissolve 2 moles of NaOH in 6 kg of water?
To dissolve 2 moles of NaOH in 6 kg of water, you would need to calculate the molarity of the NaOH solution. First, you would find the molar mass of NaOH (40 g/mol) and then divide the moles by the mass of water in kg to find the molarity. This would be approximately 0.33 mol/L.
Concentration of water in pure water?
The concentration of water in pure water is 100%, meaning that all the molecules present in the solution are water molecules.
What mass of water will contain 2.80 moles of water?
number of moles = Massdivided by Molar Mass 2.80 = Mass divided by 18.012.80 X 18.01 = MassMass = 50.43 grams.
How many moles of water were lost if the amount of water lost was 0.293 grams?
To find the number of moles of water lost, we first need to know the molar mass of water, which is approximately 18 g/mol. Then, we can use the formula moles = mass / molar mass to calculate the number of moles lost. In this case, 0.293 grams of water lost would be equivalent to approximately 0.016 moles.
How many moles of KCI would be dissolved in 4 liters of water to make a 2 Molar solution?
We need 8 moles potassium chloride.
What is the molarity of a solution that contains 0.5 moles of NaOH in 200ml water?
It is 2.5 molar. The reason for this is that molarity means moles per litre. You have to multiply by 5 to get from 200ml to a litre, so you have to do the same with the moles.
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.
How many grams of ethylene as needed to react with 0.0126 mole of water?
To determine the grams of ethylene needed to react with 0.0126 mole of water, you need to use the balanced chemical equation for the reaction between ethylene and water. Once you have the balanced equation, use the molar ratio between ethylene and water to convert moles of water to moles of ethylene. Then, use the molar mass of ethylene to convert moles of ethylene to grams of ethylene.
What is the molar concentration of 80 g of glucose dissolved in sufficient water to make 2 L of a solution?
The equation to find molar concentration is C= n/v (concentration= moles/volume). For 80g of glucose, you would first need to find the number of moles; n= m x mm (moles= mass x molar mass). Then you can input that number into the equation C= n/v.
How many moles of water are on 72.08g of H2O?
The molecular formula of water is H2O. The atomic mass of H2O is 2(1.0) + 16.0 = 18.0Amount of H2O = mass of pure sample/molar mass = 75/18.0 = 4.17mol There are 4.17 moles of water in a 75 gram pure sample.
