What is the weight of 1 oz in grams?

  1. 15.2 grams

  2. 22.5 grams

  3. 28.4 grams

  4. 45 grams

The correct answer is: 28.4 grams

1 oz is equal to 28.4 grams. This is the standard conversion from ounces to grams. Option A, 15.2 grams, is too small of a conversion and would not be 1 oz. Option B, 22.5 grams, is closer to 1 oz but still not equal to it. Option D, 45 grams, is too large of a conversion and would not be 1 oz. Therefore, the only option that accurately converts 1 oz to grams is C, 28.4 grams.
