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 is the molar mass of the nonelectrolyte compound if a 4.305 g sample of it is dissolved in 105 g of water?
To find the molar mass of the nonelectrolyte compound, we need to use the formula: Molar mass (mass of compound / moles of compound) First, we need to find the moles of the compound by using the formula: moles mass / molar mass Given that the mass of the compound is 4.305 g and it is dissolved in 105 g of water, we can calculate the moles of the compound. Next, we can find the molar mass of the compound by rearranging the formula: Molar mass mass / moles By plugging in the values, we can calculate the molar mass of the nonelectrolyte compound.
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 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 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 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 are in 2.35g are in water?
To calculate the number of moles in 2.35g of water, first determine the molar mass of water (H2O). The molar mass of one mole of water is approximately 18.015 g/mol. Use this molar mass to convert grams to moles: 2.35g / 18.015 g/mol = 0.13 moles of water.
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.
How many moles of water are in 250.0 mL of water?
To find the number of moles of water, you first need to convert the volume (250.0 mL) to liters by dividing by 1000 (since 1 L = 1000 mL). This gives you 0.250 L. From there, you can use the molar volume of water (18.02 g/mol) and the molar mass of water (18.02 g/mol) to calculate the number of moles using the formula moles = mass/molar mass.
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 is molar its measured?
In moles of a substance dissolved in 1 L of water.
