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.

∙ 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.

Dissolve 2 moles of NaOH in 6 kg of water?
The solution has a molar concentration of 0,33.
How many moles of water were lost if the amount of water lost was 0.293 grams?
To find the number of moles of a substance the following equation could be used. n=m/M where n- number of moles m- mass of substance M- molar mass of the substance. Molar mass of water = 18 g mol-1 Accordingly, the number of moles of water lost = 0.293 g /18 g mol-1 = 0.0163 mol
How many moles of water molecules h2o are present in a 27 rams sample of water?
Divide mass of 27 g H2O by its molar mass of 18.0 g.mol−1 H2O and you get the number of moles: 1.5 mole H2O
What is the molarity of 6 moles of NaCl dissolves in 2 L of water?
Molarity is defined as moles solute/liter of solution6 moles/2 liters solution = 3 molar NOTE: This assumes no volume change and 2L is the final volume of solution.
What is the molar mass of a solute if 62 g of the solute in 125g of water produce a 5.3m solution?
n°moles solute = 5.3*0.125 = 0.6625 molar mass = 62.0/0.6625 = 93.58 g/mol
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?
The solution has a molar concentration of 0,33.
Concentration of water in pure water?
The concentration of pure water is 55 molar. In other words, 1 liter of water holds 55 moles of H2O
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 a substance the following equation could be used. n=m/M where n- number of moles m- mass of substance M- molar mass of the substance. Molar mass of water = 18 g mol-1 Accordingly, the number of moles of water lost = 0.293 g /18 g mol-1 = 0.0163 mol
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.
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.
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.
