To convert pounds to ounces, we can use the conversion factor that 1 pound is equal to 16 ounces.
Given:
- Mass of sugar = 5 pounds
We want to convert this to ounces.
Using dimensional analysis:
\[ \text{Mass in ounces} = \text{Mass in pounds} \times \left(\frac{\text{16 ounces}}{\text{1 pound}}\right) \]
Substituting the value:
\[ \text{Mass in ounces} = 5 , \text{pounds} \times \left(\frac{16 , \text{ounces}}{1 , \text{pound}}\right) \]
Calculating this:
\[ \text{Mass in ounces} = 5 \times 16 , \text{ounces} \] \[ \text{Mass in ounces} = 80 , \text{ounces} \]
Thus, the bag of sugar is 80 ounces.
