Question

One mole of any substance contains 6.022 × 1023 atoms/molecules. Number of molecules of H2SO4 present in 100 mL of 0.02M H2SO4 solution is ______.

(i) 12.044 × 1020 molecules

(ii) 6.022 × 1023 molecules

(iii) 1 × 1023 molecules

(iv) 12.044 × 1023molecules


Plzzz answer it if u know otherwise I'll report ur answer...

Answer 1

Answer:

Moles of H2SO4= Molarity of H2SO4× Volume of solution (L)

=0.02×0.1

=2×10−3 moles

No. of H2SO4 molecules =2×10−3×6.022×1023=12.044×1020 molecules

Therefore, the correct option is A.
