Question

How many atoms in 80 gram NaOH

Answer 1

Answer:

please refer to the attachment

Answer 2

Answer:3.6132×10^24

Explanation:

NaOH = 23+16+1

= 40 gram

We know that

40gm of NaOH = 6.022×10^23 molecule

So 80 GM of NaOH = 2×6.022×10^23 molecule

So total molecule are 1.2044×10^24

No of Na atom are 1.2044×10^24

No of O atom are 1.2044×10^24

No of H atom are 1.2044×10^24

Hence total no of atom are 3.6132×10^24
