First we need to know how to convert gram into ounces.
1 ounces= 28.35 grams
2.3 ounces = x grams
x = 2.3 × 28.35
x = 65.205 grams
but the answer need to be in scientific notation.
We move the decimal point one place to the left and multiply to 10¹. When we multiply using significant digits, the result of the multiplication must have the same amount of significant digits as the number with the least amount of significant digits before the operation. The number with the least amount of significant digits before the operation was 2.3 with 2 digits. So the answer is 6.5 x 10¹ grams.
Answer: 6.5 x 10¹ grams
