To convert grams of a substance to moles, you can use the following relationship:
[tex]\[ \text{Number of moles} = \frac{\text{Mass in grams}}{\text{Molar mass}} \][/tex]
Here’s the step-by-step process to convert 6 grams of fluorine to moles:
1. Determine the molar mass of fluorine:
The molar mass of fluorine (F) can be found on the periodic table, and it is approximately 19.00 grams per mole (g/mol).
2. Use the formula to find the number of moles:
Substitute the mass of fluorine and its molar mass into the formula:
[tex]\[ \text{Number of moles} = \frac{\text{Mass in grams}}{\text{Molar mass}} \][/tex]
So, for 6 grams of fluorine:
[tex]\[ \text{Number of moles} = \frac{6 \text{ grams}}{19.00 \text{ grams per mole}} \][/tex]
3. Calculate the moles:
Perform the division:
[tex]\[ \text{Number of moles} = \frac{6}{19.00} \][/tex]
[tex]\[ \text{Number of moles} \approx 0.316 \][/tex]
Therefore, 6 grams of fluorine is approximately equal to 0.316 moles of fluorine.
Let’s recap the steps in brief:
1. Determine the molar mass of fluorine (19.00 g/mol).
2. Use the formula: [tex]\(\text{Number of moles} = \frac{\text{Mass in grams}}{\text{Molar mass}}\)[/tex]
3. Substitute the values and calculate: [tex]\(\frac{6 \text{ g}}{19.00 \text{ g/mol}} \approx 0.316 \text{ moles}\)[/tex]
So, the correct conversion of 6 grams of fluorine to moles involves determining the molar mass of fluorine and using the relation:
[tex]\[\frac{6 \text{ grams}}{19.00 \text{ grams per mole}} \approx 0.316 \text{ moles}\][/tex]
