Answer 2

There are 316.46 g of Cl in 495 g of CaCl₂.

Step-by-step explanation:

• The molar mass of CaCl₂ is 40 + 35.45 + 35.45 = 110.9 g/mol

• Moles of CaCl₂ present in 495 g of CaCl₂ = 495 g ÷ 110.9 g/mol = 4.46 mol CaCl₂

With that data we can calculate the moles of Cl, and then convert them into grams:

4.46 mol CaCl₂ *
`(2molCl)/(1molCaCl_(2))` *
`(35.45g)/(1molCl)` = 316.46 g of Cl
