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.
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
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 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.
What is the mass of 0.5 moles of water?
The mass of 0,5 moles of water is 9 g.
How do you calculate the moles of water?
To calculate the moles of water, you can use the formula: moles = mass of water (in grams) / molar mass of water (about 18.015 g/mol). Simply divide the mass of water by its molar mass to find the number of moles.
How would you find out how much 12.4 moles of water weigh?
Multiply moles by molecular mass of water (18), gives you 223.8g. Remember this formula: Number of moles = mass / molecular mass
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 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.
What mass of water is 2.000 mol of water?
The mass of 2 moles of water is 36 g.
How many moles are in 40.0g of h20?
The molar mass of water (H2O) is approximately 18.02 g/mol. To find the number of moles in 40.0 g of water, you would divide 40.0 g by the molar mass of water. This would give you approximately 2.22 moles of water.
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 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 3.2 moles of water?
The molar mass of water (H2O) is approximately 18.015 g/mol. To find the mass of 3.2 moles of water, you multiply the number of moles by the molar mass: 3.2 moles x 18.015 g/mol = 57.648 g. So, the mass of 3.2 moles of water is approximately 57.648 grams.
What is the mass of 2 moles of water (H2O)?
A mole of HNO3 weighs 63g (1 + 14 +16x3). Therefore, two moles weigh, 2 x 63 =126 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.
