Question

Calculate the number of atom in
each of following:
a, 16 mres of the
b)16 u of Hl

Answer 1

Answer:

To calculate the number of atom

1.First we convert it into grams

2.Then divide these grams by molar mass of an aton or molecule

3. After this we multiple number of moles with avogadro's numbes. End result is the number of atom of that atom or molecule

A. atom or molecule is not mentioned

B.

16u= 2.657 × 10^-23 grams

moles=2.657×10^-23/128

answer ×6.023×10^23

I hope it will help you
