To convert to scientific notation, we move the decimal point until there is only one non-zero digit to the left of the decimal point. We then count the number of decimal places we moved the decimal point and express it as a power of 10. Starting with 0.000007913 g, we move the decimal point 6 places to the right to get 7.913, giving us 7.913 x 10^-6 g. This is equivalent to answer choice D, where the exponent of 10 is -6.
