Question

in 12g of carbon, there are 6.02*10^23 carbon atoms. if you could count 1 atom per second how long would it take to count the atoms in 1g of carbon?

Answer 1

Answer:

here, in 12g we have 6.023 ×10²³

Explanation:

so for 1g we have 6.023 ×10²³/12

= 0.50×10²³

given we can count 1 atom per sec

so for 0.5 ×10²³ atoms

we can count them in 0.5×10²³ sec

which can be written as 5×10²²

hope it helps you
