Question

1. It one mole of carbon atoms weighs 12 grams, what
is the mass (in grams) of 1 atom of carbon?​

Answer 1

Explanation:

A mole is defined as exactly equal to 6.022×1023 atoms. So, we know that a mole of carbon contains 6.022×1023 atoms. Therefore, we can write the mass of 6.022×1023 atoms = 12 g. Hence, the mass in grams of 1 atom of carbon is 1.993×10−23g .

Answer 2

Answer:

1 mole of carbon contain 6.022×10²³ atoms

so mass of 1 atom=12/6.022×10²³

= hence mass of 1 atom will be 1.99×10-²³ (appx)
