## How many chloride ions are in 2.5 moles of CaCl2?

The molecular formula of calcium chloride is CaCl2, which means that each mole of salt contains one mole of calcium and two moles of chlorine. If then 2.5 moles of CaCl2 dissolved in a suitable solvent are obtained, 2.5 moles of calcium ions (1×2. 5) and 5 moles of chloride ions (2×2.

## How many moles are in CaCl2?

The molar mass of CaCl2 is 110.98 g/mol. The conversion factor that can be used is then based on the equality that 1 mol = 110.98 g CaCl2. Dimensional analysis will allow you to calculate the mass of CaCl2 that you should measure. When you measure the mass of 333 g of CaCl2, you are measuring 3.00 moles of CaCl2.

## What is the mass of 2.5 mole of Cl2?

Answer: Cl2 contains two Cl atom so molar mass will be 35 . 5 x2 that is 71 GRAM means 0ne mole of Cl2 has 71 gram so 2.5 mol will be equal to 2.5×71. Gram.

## How do you find the molar mass of CaCl2?

Molecular formula is CaCl2 i.e. 1 atom of Ca and 2 atoms of Cl . Hence, molecular weight = 1 x 40 + 2 x 35.5 = 40 + 71 = 111 g / mol .

## How many grams of CaCl2 are in 250 ml of 2.0 M CaCl2?

The solution contains 0.50 mol or 55 g of CaCl2 . You know there are 2.0 mol of CaCl2 in 1 L of solution. (40.08 + 2 × 35.45) g=(40.08 + 70.90) g=110.98 g .

## How many moles of CaCl2 are in CaCl2 2H2O?

THe istructions are: Calculate how many moles of CaCl2•2H2O are present in 1.50 g of CaCl2•2H2O and then calculate how many moles of pure CaCl2 are present in the 1.50 g of CaCl2•2H2O.

Initial: CaCl2 x 2H20 (g) 1.50 g
Actual: CaCO3 (g) 1.4 g
