Answer:

the length of pennies will be like the Proxima Centauri

Explanation:

50 pennies make the length of a meter, so :

50 pennies = 1 m

   x               = 1 km  

x= (50 x 1000) = 50 000 pennies = 1 Km

Then if the Avogadro´s number is 6.022 x 1023 so:

50 000 pennies = 1 km

6.022 x 1023 pennies = x

x= (6.022 x 1023/ 50 000) = 1.2044 x 1019

This big number is closer to the 40 trillion km of the Proxima Centauri.

Hope this answer is useful.
