Question

Number of nucleons in 50 atom of an element is 2700. Calculate mass in gram of 2 mole of atom of an element​

Answer 1

Answer:

1mol = 16gm

Explanation:

in 1g= 1/32 = 0.0625

No atoms = 0.0625 × (6.023 × 10 raise to 23) =

3.76×10raise to 22 atoms of O.

option B: O2

1mole of O2 = 16×2= 32g

1g = 1/32 = 0.0313 moles

therefore,
