ANSWER

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

Posted by Santosh Patel Patel 3 years, 9 months ago

Sia ? 3 years, 9 months ago

We have given that one mole of carbon atom weighs 12 g.
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.
Using the unitary method to find the mass of 1 atom of carbon in grams. So, we can write as below-
So, now mass of 1 atom of carbon will be =12 / (6.022 × 10²³) = 1.993 × 10⁻²³ g
Hence, the mass in grams of 1 atom of carbon is 1.993 × 10⁻²³g.
If we have to find the mass of 2 atoms or n number of carbon atoms, the same way we can proceed to find the mass in grams of the carbon atoms.

Radhika Soni 3 years, 9 months ago

Growth in plants occurs as the stems and roots lengthen. Some plants, especially those that are woody, also increase in thickness during their life span. The increase in length of the shoot and the root is referred to as primary growth, and is the result of cell division in the shoot apical meristem.
