One hundred million copper atoms are arranged in a line. Which is a reasonable estimate for the length of this line?
1 kilometer
1 nanometer
1 centimeter
1 meter​

Respuesta :

The size of an atom is roughly 10^-10 metres

10^-10 • 100,000,000 = 0.01 metres

Since 1 metre = 100 centimetre

0.01 x 100 = 1 centimetre

There’s your answer
