calculate the number of nucleons present in 24.5 g of king of chemicals
1) 0.737×10^25. 2) 1.474 ×10^25
3) 2.212×10^25. 4) 4.422×10^25
Answers
Dear Student,
● Answer -
(2) 1.474 ×10^25
◆ Explanation -
Sulphuric acid is the king of chemicals. Molar mass of sulphuric acid is 98 g/mol.
No of moles of sulphuric acid is -
No of moles = 24.5 / 98
No of moles = 0.25 mol
No of molecules of sulphuric acid is -
No of molecules = 0.25 × 6.022×10^23
No of molecules = 1.5055×10^23
No of nucleons is -
No of nucleons -
No of nucleons = 98 × 1.5055×10^23
No of nucleons = 1.475×10^25
Thanks dear. Hope this helps you..
