The molarity is 2 mol/L.
20.2 g of CuCl2 = .1502 mol CuCl2 M=mol/L M=.1502 mol/L
The formula mass of (anhydrous) CaCl2 is: 110,99 g/mol;as dihydrate CaCl2.2H2O it is: 147,01 g/mol
The gram formula mass of CaCl2 is approximately 110.98 g/mol. This is calculated by adding the atomic masses of the elements in the compound, which are 40.08 g/mol for calcium (Ca) and 35.45 g/mol for each chlorine (Cl) atom.
To find the number of molecules in 1.46 moles of CaCl2, you would first calculate the molar mass of CaCl2 (110.98 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. This would give you approximately 8.80 x 10^23 molecules of CaCl2.
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kilograms. In this case, the molality of the CaCl2 solution would be 2 mol/kg, as 6 mol of CaCl2 dissolved in 3 kg of water results in a molality of 2 mol/kg.
2 m is the molarity of a solution that has 6 mol of CaCl2 in 3 km of water.

The molarity is 2 mol/L.
When CaCl2 dissociates in water, it forms three ions: one Ca2+ ion and two Cl- ions for each formula unit of CaCl2. Therefore, 0.50 mol of CaCl2 would yield 0.50 mol Ca2+ ions and 1.0 mol Cl- ions in solution, totaling 1.5 moles of ions.
20.2 g of CuCl2 = .1502 mol CuCl2 M=mol/L M=.1502 mol/L
molarity is #moles divide by # liters, so 3.0 divided by 0.500 is 6.0 molarity (2 siginficant figures is all you are allowed)
First, calculate the molar mass of CaCl2, which is 110.98 g/mol. Next, calculate the number of moles of CaCl2 in 330 grams using the formula moles = mass / molar mass. This gives you 2.97 mol of CaCl2. Finally, divide the moles of CaCl2 by the volume of the solution in liters to get the molarity, which is 2.97 M.
To find the moles of solute, first calculate the amount of CaCl2 in the solution: 17.33 mL * 2.17 mol/L = 37.6561 mmol of CaCl2. Then convert this to moles: 37.6561 mmol / 1000 = 0.0377 mol of CaCl2 in the solution.
To make 1 liter of a 1 molar solution of CaCl2, you would need to dissolve 147.02 grams of CaCl2 in enough water to make a final volume of 1 liter. This formula weight comes from the atomic weights of calcium (40.08 g/mol) and chlorine (35.45 g/mol).
To find the mass of 0.89 mol of CaCl2, you need to multiply the molar mass of CaCl2 by 0.89 mol. The molar mass of CaCl2 is 110.98 g/mol. Therefore, the mass of 0.89 mol of CaCl2 would be 98.882 g.
The gram formula mass of CaCl2 is 110.99. By definition, each liter of 0.700 M CaCl2 contains 0.700 gram formula masses of the solute. Therefore, 2.00 liters of such solution contain 1.400 formula masses of the solute, or 155 grams, to the justified number of significant digits.
