a.
b.
c. "Nano" is 10⁻⁹ , so there are 10⁻⁹ meter in a nm (OR) "Nano" is 10⁻⁹ , so there are 10⁹ nm in a meter.
d. micro is 10⁻⁶, so 1kg is 10⁹ ug
Explanation:

b.
The values in the conversion factor used are wrong. The correct statement will be:
c.
Change of units is the mistake here. The correct statement will be:
<u>"Nano" is 10⁻⁹ , so there are 10⁻⁹ meter in a nm (OR) "Nano" is 10⁻⁹ , so there are 10⁹ nm in a meter.</u>
d.
the conversion will be as follows:
therefore, the correct statement will be:
