Quizplus · Accepted Answer

The given mass can be expressed in scientific notation as 9.28 x 10^-23 g. This is because the decimal point should be moved 23 places to the left to obtain a number between 1 and 10, and the exponent should be negative since the given mass is less than 1 gram. Therefore, the correct answer is D, 9.28 x 10^-23 g.
