1. Freon (CCl2F2) is commonly used in refrigerators and air conditioners as a coolant. How many grams of fluorine are there in t

Georgia [21]

Answer:

285g of fluorine

Explanation:

To solve this problem we need to find the mass of Freon in grams. Then, with its molar mass we can find moles of freon and, as 1 mole of Freon, CCl₂F₂, contains 2 moles of fluorine, we can find moles of fluorine and its mass:

<em>Mass Freon:</em>

<em>2.00lbs * (454g / 1lb) = </em>908g of Freon

<em>Moles freon -Molar mass: 120.91g/mol- and moles of fluorine:</em>

908g of Freon * (1mol / 120.91g) =

7.5 moles of freon * (2moles Fluorine / mole Freon): 15 moles of fluorine

<em>Mass fluorine -Atomic mass: 19g/mol-:</em>

15 moles F * (19g / mol) =

<h3>285g of fluorine</h3>
