1g of charcoal having surface area 3 02*10 m is mixed in 100 ml of 0 5 M acetic acid - Chemistry - Surface Chemistry

Question

1g of charcoal having surface area 3 02*10?m?is mixed in 100 ml of
0 5 M acetic acid solution; after few times concentration of
solution becomes 0 49 M what will be surface area occupied one
molecule of acetic acid ?

Mansi · Answer

moles=molarity x volume (L)
= (0 5 - 0 49) x 100 x 10-3
= 10-3 moles
= 10-3 x NA
= 6 02 x 1020 molecules
