Identify the given number: 0.00016 kg.
To express this number in scientific notation, move the decimal point to the right until you have a number between 1 and 10. In this case, move the decimal point 4 places to the right, which gives you 1.6.
Count the number of places you moved the decimal point. Since you moved it 4 places to the right, the exponent will be -4.
Combine the number and the exponent to express the original number in scientific notation: 1.6 × 10-4 kg.
Verify that the scientific notation correctly represents the original number by converting it back to decimal form: 1.6 × 10-4 = 0.00016 kg.
