Question

The number of s=o and s-oh bonds present in peroxodisulphuric acid and pyrosulphuric acid respectively by intext:zigya gbshse

Answer 1

It has two solutions :

No of moles of the substance = weight/atomic mass. So 12g of carbon12 atom has 6.023*10^23 atoms . No

of protons electrons neutrons present in one carbon atom = 6. No of protons electrons neutrons present in 12 gram of carbon atom is 6*6.023*10^23 = 36.138*10^23. The question says no of protons,electrons and neutrons present in it. Therefore the answer is 3*36.138*10^23 = 1.08*10^25

Or

12 g carbon contains 6.022 * 1023 atoms. One atom contain 6 protons, 6 neutrons, 6 electrons.

So number of protons, electrons and neutrons in 12 g carbon = 6.022 * 1023 * 6
