Question

Calculate the no. Of moles, atoms of h,s,o in 5 moles of h2so4 with explanation

Answer 1

Answer:

Number of moles = weight/molar mass

weight of H2SO4 = number of molesXmolar mass

weight of H2SO4 = 5 X 98

therefore weight of H2SO4 is 490

Number of atoms

= moles X Avogadro's number X atomicity

Number of atoms of H

= 5 X 6.022 X 10²³ X 2

= 6.022 X 10²²

Number of atoms of S

= 5 X 6.022 X 10²³ X 1

= 3.011 X 10²²

Number of atoms of O

= 5 X 6.022 X 10²³ X 4

= 1.204 X 10²¹

Answer 2

Answer:

above answer is not fully correct because power is subtracted not added as they are in multiply like 5× 6.02×10²³ ×2= 6.022×10²⁴ will come and final answer of this question has 10²⁵ but his answer has 10²¹
