If you start with 5.5 grams of sodium fluoride, how many grams of magnesium fluoride will be produced in the reaction #Mg + 2NaF -> MgF_2 + 2Na#?
There will be 4.1 g of
5.5 grams of sodium fluoride in mass
This will now be converted to grams.

To find out how many grams of magnesium fluoride (MgF_2) will be produced from 5.5 grams of sodium fluoride (NaF), we'll first need to calculate the molar masses of NaF and MgF_2 using the atomic masses of the elements involved (Na = 22.99 g/mol, F = 19.00 g/mol, Mg = 24.31 g/mol).
- Molar mass of NaF: 22.99 g/mol (Na) + 19.00 g/mol (F) = 41.99 g/mol
- Molar mass of MgF_2: 24.31 g/mol (Mg) + 2(19.00 g/mol (F)) = 62.31 g/mol
Given 5.5 grams of NaF:
- First, calculate the moles of NaF: [ \text{Moles of NaF} = \frac{5.5 , \text{grams}}{41.99 , \text{g/mol}} ]
[ \text{Moles of NaF} = 0.131 , \text{moles} ]
Since the reaction shows that 2 moles of NaF react with Mg to produce 1 mole of MgF_2, the moles of MgF_2 produced will be half the moles of NaF.
-
Calculate the moles of MgF_2 produced: [ \text{Moles of MgF}_2 = 0.131 / 2 = 0.0655 , \text{moles} ]
-
Finally, calculate the mass of MgF_2 produced: [ \text{Mass of MgF}_2 = 0.0655 , \text{moles} \times 62.31 , \text{g/mol} ]
[ \text{Mass of MgF}_2 = 4.08 , \text{grams} ]
Therefore, 4.08 grams of magnesium fluoride will be produced.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
