How many grams of CaCl2 are in 3 moles of CaCl2?

And thus 3 mol of CaCl2 have a mass of 3⋅mol ×110.98⋅g⋅mol−1 ≅ 333⋅g .

What is the mass of 1 mole of CaCl2?

In CaCl2, the chemical formula tells us that there are two moles of Cl1- in every mole of compound, and three moles of total ions (1 mole Ca2+, 2 moles Cl1-) in every mole of compound.

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 .

What is the molar mass of CaCl2 6H2O?

Molar mass of CaCl2. 6H2O = 219.07568 g/mol. This compound is also known as Calcium Chloride Hexahydrate.

How many grams is 2 moles 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 are contained in 48 g mg?

Therefore, number of atoms in 48 g of Mg = 2 mol $ times $ $6.022 times {10^{23}}$atoms/mol= [12.04 times {10^{23}}] atoms. Thus, 48 g of Mg is equivalent to $12.04 times {10^{23}}$ atoms. Hence, option A is the correct answer.
