3. If one kilogram weighs about 35 ounces, how many grams (g) are there in 2 ounces? (Round to the nearest gram)

Answer: D

Explanation:

There are 57 grams in 2 ounces.

To convert ounces to grams, we can use the conversion factor that 1 ounce is approximately 28.35 grams. Therefore, 2 ounces equals about 57 grams when calculated.

A) 56 g

This option is incorrect because 56 grams would result from multiplying 2 ounces by a slightly lower conversion factor. The accurate calculation shows that 2 ounces is approximately 57 grams.

B) 58 g

58 grams is also incorrect as it exceeds the correct conversion. The calculation of 2 ounces using the accurate conversion factor yields a value closer to 57 grams rather than 58 grams.

C) 59 g

This option is incorrect since it overestimates the weight of 2 ounces. The proper conversion calculation indicates a weight closer to 57 grams, not 59 grams.

D) 57 g

This is the correct answer. By multiplying 2 ounces by the conversion factor of 28.35 grams per ounce, we arrive at approximately 57 grams, which is the correct rounded value.

Conclusion

The correct answer is 57 grams, as derived from the accurate conversion of ounces to grams. All other options fail to reflect the precise calculation based on the standard conversion factor, making D the definitive choice.
