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>
There are 4 significant digits: 3405.
The name of the compound NiSO4 • 5H2O is <u>nickel (II) sulfate pentahydrate.</u> Since there is <span> a transition metal cation with multiple oxidation states, you have to include the Roman numeral in the brackets.
Ni is nickel, so the first part is obvious. Since there are four equivalent oxygen atoms in a tetrahedral arrangement, it is also a sulfate. Penta refers to number 5, and hydrate because it consists water.</span>
