How many moles of ions are released when 42.1g of CuSO4is dissolved in water?
The number of moles is 0,527.
What is the molarity of a solution which contains 2 moles of glycerin dissolved in 1000g of water?
Well the definition of molarity is how many moles in every litre. You already have your answer expressed as moles in a litre, approximately. Density is approximately 1000g per litre, therefore it will be approximately 2 molar. (You haven't expressed temperature, but density should remain close to 1).
How many moles of water are contained in one mole of this hydrate in alum containing 45 percent water?
The moles number of water 12; the chemical formula is KAl(SO4)2.12H2O.
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 does C7H8 have?
If there is no number in front of the formula, the number of moles is understood to be one.
How many liters are in 0.82 moles?
Roughly zero. One litre is more water than I can drink in one go, and 0.82 moles of water is too small to see.
What are percents in molarity?
Assume purity unless otherwise stated. Find out the density and apply it to 1 litre to find out how many grams a litre will weigh. divide this answer by the molecular weight to get the number of moles in a litre
How many moles of ions are released when 42.1g of CuSO4is dissolved in water?
The number of moles is 0,527.
How many moles of KCl are contained in a 0.630L of a 2.3M KCl solution?
To find the moles of KCl in the solution, we use the formula: Moles = Molarity x Volume (in liters). Plugging in the values, Moles = 2.3 mol/L x 0.630 L = 1.449 mol of KCl in 0.630 L of a 2.3M KCl solution.
What is the molarity of a solution which contains 2 moles of glycerin dissolved in 1000g of water?
Well the definition of molarity is how many moles in every litre. You already have your answer expressed as moles in a litre, approximately. Density is approximately 1000g per litre, therefore it will be approximately 2 molar. (You haven't expressed temperature, but density should remain close to 1).
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 molecules of water are in 5.65 moles of water?
A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.
How many moles of water in ml of water?
The answer is 6 moles.
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 are present in 180.00 gm of water?
9.991 Moles (water) 8.982 Moles (heavy water)
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 there in 1.792 L?
95,474 moles
