Question

No. of oxalic acid molecules in 100 ml of 0.02 N
oxalic acid is -
(A) 6.023 x 1020 (B) 6.023 x 1021
(C) 6.023 102 (D) 6,023 x 1023
​

Answer 1

answer is option in the that is 6.023 into 10 to the power 23 Ee has molarity of the solution is equal to 0.02 divided by to which becomes 0.01 which x 100 gives us 1 and which multiplied by Avogadro's number gives us Avogadro's number of molecules which gives us that is 6.023 into 10 to the power 23 molecules
