Many atomic dimensions are expressed in angstroms (a). (1a = 1 x 10-8cm). what is the angstrom equal to in terms of the si units nanometer (nm) and picometer (pm)? report your answers in scientific notation.

1 Å = 1.0 × 10⁻¹ nm

1 Å = 1.0 × 10² pm

Explanation:

Angstrom is the unit of the length which is equal to one ten-billionth of the metre or 10⁻¹⁰ m. It is represented by the symbol is Å .

Angstrom is not part of SI system of the units, but it is considered as a part of metric system.  

Angstrom is used often in natural sciences as well as technology in order to express the sizes of atoms / molecules, and the lengths of the chemical bonds, etc.

1 Å = 10⁻¹⁰ m

1 nm = 10⁻⁹ m

1 pm = 10⁻¹² m

So,  

1 Å = 1.0 × 10⁻¹ nm

1 Å = 1.0 × 10² pm

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
