A nutritional label says that a serving of mac and cheese is 121 grams. How many ounces are in a serving? ounces
Use $1\mathrm{oz}=28.35\mathrm{g}$

Step 1 ：Given that Australia is approximately 2555 miles in width, we can convert this to kilometers using the conversion factor $1\mathrm{km}=0.6214\mathrm{mi}$. This gives us $\frac{2555}{0.6214}\approx 4111.68$ kilometers.

Step 2 ：Angela bought 8 bottles of soda for a party, each bottle was 2 liters, giving a total of $8\times 2=16$ liters. We can convert this to gallons using the conversion factor $1\mathrm{gallon}=3.785\mathrm{liters}$. This gives us $\frac{16}{3.785}\approx 4.23$ gallons.

Step 3 ：Camille was in a 3000 meter race. We can convert this to miles using the conversion factor $1\mathrm{mi}=1609.24\mathrm{m}$. This gives us $\frac{3000}{1609.24}\approx 1.86$ miles.

Step 4 ：A nutritional label says that a serving of mac and cheese is 121 grams. We can convert this to ounces using the conversion factor $1\mathrm{oz}=28.35\mathrm{g}$. This gives us $\frac{121}{28.35}\approx 4.27$ ounces.

Step 5 ：$\boxed{{\displaystyle \text{Final Answer:}}}$ Australia is approximately $\boxed{{\displaystyle 4111.68}}$ kilometers wide. Angela bought $\boxed{{\displaystyle 4.23}}$ gallons of soda. The race was $\boxed{{\displaystyle 1.86}}$ miles long. A serving of mac and cheese is $\boxed{{\displaystyle 4.27}}$ ounces.
