it depends on the widths of the recesses, and if it is causing the shelf to fracture and collapse into the sea, then a massive iceberg could be called from the life she,f and the ice shelf are way more important because it holds it up
The correction according to the Van Dee Walls equation is Vn-b
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>
33060 grams of magnesium nitrate would be produced from with 3.421 X 10²⁶ formula units of magnesium hydroxide.
<h3>HOW TO CALCULATE MASS?</h3>
The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass.
However, the number of moles of magnesium hydroxide must be calculated by dividing the formula units by Avogadro's number.
no. of moles = 3.421 X 10²⁶ ÷ 6.02 × 10²³
no. of moles = 0.57 × 10³
no. of moles = 5.7 × 10²moles
Molar mass of Mg(OH)2 = 24 + 34 = 58g/mol
mass of Mg(OH)2 = 570 moles × 58g/mol
mass of Mg(OH)2 = 33060g
Therefore, 33060 grams of magnesium nitrate would be produced from with 3.421 X 10²⁶ formula units of magnesium hydroxide.

Since you have the same amount of ingredients, you have to divide the number by the larger number because it is being decreased at a faster rate
